Definitions

  • the present invention relates to compounds, prodrugs, and methods of using these compounds and prodrugs thereof in the treatment of conditions in which modulation of the JAK pathway or inhibition of JAK kinases, particularly JAK3, are therapeutically useful.
  • Protein kinases constitute a large family of structurally related enzymes that are responsible for the control of a variety of signal transduction processes within cells (see, e.g., Hardie and Hanks, The Protein Kinase Facts Book, I and II, Academic Press, San Diego, Calif., 1995). Protein kinases are thought to have evolved from a common ancestral gene due to the conservation of their structure and catalytic function. Almost all kinases contain a similar 250-300 amino acid catalytic domain. The kinases can be categorized into families by the substrates they phosphorylate (e.g., protein-tyrosine, protein-serine/threonine, lipids, etc.).
  • JAK kinases are a family of cytoplasmic protein tyrosine kinases including JAK1, JAK2, JAK3 and TYK2. Each of the JAK kinases is selective for the receptors of certain cytokines, though multiple JAK kinases can be affected by particular cytokine or signaling pathways. Studies suggest that JAK3 associates with the common gamma ( ⁇ c) chain of the various cytokine receptors. JAK3 in particular selectively binds to receptors and is part of the cytokine signaling pathway for IL-2, IL-4, IL-7, IL-9, IL-15 and IL-21.
  • ⁇ c common gamma
  • JAK1 interacts with, among others, the receptors for cytokines IL-2, IL-4, IL-7, IL-9 and IL-21
  • JAK2 interacts with, among others, the receptors for IL-9 and TNF- ⁇ .
  • cytokines e.g., IL-2, IL-4, IL-7, IL-9, IL-15 and IL-21
  • receptor oligomerization occurs, resulting in the cytoplasmic tails of associated JAK kinases being brought into proximity and facilitating the trans-phosphorylation of tyrosine residues on the JAK kinase. This trans-phosphorylation results in the activation of the JAK kinase.
  • STAT proteins which are DNA binding proteins activated by phosphorylation of tyrosine residues, function both as signaling molecules and transcription factors and ultimately bind to specific DNA sequences present in the promoters of cytokine-responsive genes (Leonard et al., (2000), J. Allergy Clin. Immunol. 105:877-888).
  • JAK/STAT signaling has been implicated in the mediation of many abnormal immune responses such as allergies, asthma, autoimmune diseases such as transplant (allograft) rejection, rheumatoid arthritis, amyotrophic lateral sclerosis and multiple sclerosis, as well as in solid and hematologic malignancies such as leukemia and lymphomas.
  • autoimmune diseases such as transplant (allograft) rejection, rheumatoid arthritis, amyotrophic lateral sclerosis and multiple sclerosis
  • solid and hematologic malignancies such as leukemia and lymphomas.
  • JAK3 in particular has been implicated in a variety of biological processes. For example, the proliferation and survival of murine mast cells induced by IL-4 and IL-9 have been shown to be dependent on JAK3- and gamma chain-signaling (Suzuki et al., (2000), Blood 96:2172-2180). JAK3 also plays a crucial role in IgE receptor-mediated mast cell degranulation responses (Malaviya et al., (1999), Biochem. Biophys. Res. Commun. 257:807-813), and inhibition of JAK3 kinase has been shown to prevent type I hypersensitivity reactions, including anaphylaxis (Malaviya et al., (1999), J. Biol. Chem.
  • JAK3 inhibition has also been shown to result in immune suppression for allograft rejection (Kirken, (2001), Transpl. Proc. 33:3268-3270). JAK3 kinases have also been implicated in the mechanism involved in early and late stages of rheumatoid arthritis (Muller-Ladner et al., (2000), J. Immunol. 164:3894-3901); familial amyotrophic lateral sclerosis (Trieu et al., (2000), Biochem Biophys. Res. Commun. 267:22-25); leukemia (Sudbeck et al., (1999), Clin. Cancer Res.
  • JAK kinases are abundantly expressed in primary leukemic cells from children with acute lymphoblastic leukemia, the most common form of childhood cancer, and studies have correlated STAT activation in certain cells with signals regulating apoptosis (Demoulin et al., (1996), Mol. Cell. Biol. 16:4710-6; Jurlander et al., (1997), Blood. 89:4146-52; Kaneko et al., (1997), Clin. Exp. Immun. 109:185-193; and Nakamura et al., (1996), J. Biol. Chem. 271:19483-8). They are also known to be important to lymphocyte differentiation, function and survival.
  • JAK-3 in particular plays an essential role in the function of lymphocytes, macrophages, and mast cells.
  • compounds which modulate the JAK pathway including those selective for JAK3, can be useful for treating diseases or conditions where the function of lymphocytes, macrophages, or mast cells is involved (Kudlacz et al., (2004) Am. J. Transplant 4:51-57; Changelian (2003) Science 302:875-878).
  • Conditions in which targeting of the JAK pathway or modulation of the JAK kinases, particularly JAK3, are contemplated to be therapeutically useful include, leukemia, lymphoma, transplant rejection (e.g., pancreas islet transplant rejection, bone marrow transplant applications (e.g., graft-versus-host disease), autoimmune diseases (e.g., diabetes), and inflammation (e.g., asthma, allergic reactions). Conditions which can benefit for inhibition of JAK3 are discussed in greater detail below.

I. INTRODUCTION
A. Field
The present invention relates to compounds, prodrugs, and methods of using these compounds and prodrugs thereof in the treatment of conditions in which modulation of the JAK pathway or inhibition of JAK kinases, particularly JAK3, are therapeutically useful.
B. Background
Protein kinases constitute a large family of structurally related enzymes that are responsible for the control of a variety of signal transduction processes within cells (see, e.g., Hardie and Hanks, The Protein Kinase Facts Book, I and II, Academic Press, San Diego, Calif., 1995). Protein kinases are thought to have evolved from a common ancestral gene due to the conservation of their structure and catalytic function. Almost all kinases contain a similar 250-300 amino acid catalytic domain. The kinases can be categorized into families by the substrates they phosphorylate (e.g., protein-tyrosine, protein-serine/threonine, lipids, etc.). Sequence motifs have been identified that generally correspond to each of these families (see, e.g., Hanks & Hunter, (1995), FASEB J. 9:576-596; Knighton et al., (1991), Science 253:407-414; Hiles et al., (1992), Cell 70:419-429; Kunz et al., (1993), Cell 73:585-596; Garcia-Bustos et al., (1994), EMBO J. 13:2352-2361).
JAK kinases (JAnus Kinases) are a family of cytoplasmic protein tyrosine kinases including JAK1, JAK2, JAK3 and TYK2. Each of the JAK kinases is selective for the receptors of certain cytokines, though multiple JAK kinases can be affected by particular cytokine or signaling pathways. Studies suggest that JAK3 associates with the common gamma (γc) chain of the various cytokine receptors. JAK3 in particular selectively binds to receptors and is part of the cytokine signaling pathway for IL-2, IL-4, IL-7, IL-9, IL-15 and IL-21. JAK1 interacts with, among others, the receptors for cytokines IL-2, IL-4, IL-7, IL-9 and IL-21, while JAK2 interacts with, among others, the receptors for IL-9 and TNF-α. Upon the binding of certain cytokines to their receptors (e.g., IL-2, IL-4, IL-7, IL-9, IL-15 and IL-21), receptor oligomerization occurs, resulting in the cytoplasmic tails of associated JAK kinases being brought into proximity and facilitating the trans-phosphorylation of tyrosine residues on the JAK kinase. This trans-phosphorylation results in the activation of the JAK kinase.
Phosphorylated JAK kinases bind various STAT (Signal Transducer and Activator of Transcription) proteins. STAT proteins, which are DNA binding proteins activated by phosphorylation of tyrosine residues, function both as signaling molecules and transcription factors and ultimately bind to specific DNA sequences present in the promoters of cytokine-responsive genes (Leonard et al., (2000), J. Allergy Clin. Immunol. 105:877-888). JAK/STAT signaling has been implicated in the mediation of many abnormal immune responses such as allergies, asthma, autoimmune diseases such as transplant (allograft) rejection, rheumatoid arthritis, amyotrophic lateral sclerosis and multiple sclerosis, as well as in solid and hematologic malignancies such as leukemia and lymphomas. For a review of the pharmaceutical intervention of the JAK/STAT pathway see Frank, (1999), Mol. Med. 5:432:456 and Seidel et al., (2000), Oncogene 19:2645-2656.
JAK3 in particular has been implicated in a variety of biological processes. For example, the proliferation and survival of murine mast cells induced by IL-4 and IL-9 have been shown to be dependent on JAK3- and gamma chain-signaling (Suzuki et al., (2000), Blood 96:2172-2180). JAK3 also plays a crucial role in IgE receptor-mediated mast cell degranulation responses (Malaviya et al., (1999), Biochem. Biophys. Res. Commun. 257:807-813), and inhibition of JAK3 kinase has been shown to prevent type I hypersensitivity reactions, including anaphylaxis (Malaviya et al., (1999), J. Biol. Chem. 274:27028-27038). JAK3 inhibition has also been shown to result in immune suppression for allograft rejection (Kirken, (2001), Transpl. Proc. 33:3268-3270). JAK3 kinases have also been implicated in the mechanism involved in early and late stages of rheumatoid arthritis (Muller-Ladner et al., (2000), J. Immunol. 164:3894-3901); familial amyotrophic lateral sclerosis (Trieu et al., (2000), Biochem Biophys. Res. Commun. 267:22-25); leukemia (Sudbeck et al., (1999), Clin. Cancer Res. 5:1569-1582); mycosis fungoides, a form of T-cell lymphoma (Nielsen et al., (1997), Prac. Natl. Acad. Sci. USA 94:6764-6769); and abnormal cell growth (Yu et al., (1997), J. Immunol. 159:5206-5210; Catlett-Falcone et al., (1999), Immunity 10:105-115).
The JAK kinases, including JAK3, are abundantly expressed in primary leukemic cells from children with acute lymphoblastic leukemia, the most common form of childhood cancer, and studies have correlated STAT activation in certain cells with signals regulating apoptosis (Demoulin et al., (1996), Mol. Cell. Biol. 16:4710-6; Jurlander et al., (1997), Blood. 89:4146-52; Kaneko et al., (1997), Clin. Exp. Immun. 109:185-193; and Nakamura et al., (1996), J. Biol. Chem. 271:19483-8). They are also known to be important to lymphocyte differentiation, function and survival. JAK-3 in particular plays an essential role in the function of lymphocytes, macrophages, and mast cells. Given the importance of this JAK kinase, compounds which modulate the JAK pathway, including those selective for JAK3, can be useful for treating diseases or conditions where the function of lymphocytes, macrophages, or mast cells is involved (Kudlacz et al., (2004) Am. J. Transplant 4:51-57; Changelian (2003) Science 302:875-878). Conditions in which targeting of the JAK pathway or modulation of the JAK kinases, particularly JAK3, are contemplated to be therapeutically useful include, leukemia, lymphoma, transplant rejection (e.g., pancreas islet transplant rejection, bone marrow transplant applications (e.g., graft-versus-host disease), autoimmune diseases (e.g., diabetes), and inflammation (e.g., asthma, allergic reactions). Conditions which can benefit for inhibition of JAK3 are discussed in greater detail below.
In view of the numerous conditions that are contemplated to benefit by treatment involving modulation of the JAK pathway it is immediately apparent that new compounds that modulate JAK pathways and methods of using these compounds should provide substantial therapeutic benefits to a wide variety of patients.

Prodrugs are typically obtained by masking one or more functional groups in an active 2,4-pyrimidinediamine drug believed to be in part required for activity with a progroup (defined below) to form a promoiety which undergoes a transformation, such as cleavage, under the specified conditions of use to release the functional group, and hence the active 2,4-pyrimidinediamine drug. The cleavage of the promoiety may proceed spontaneously, such as by way of a hydrolysis reaction, or it can be catalyzed or induced by another agent, such as an enzyme, light, an acid or base, or a change of or exposure to a physical or environmental parameter, such as temperature. The agent can be endogenous to the conditions of use, such as an enzyme present in the cells to which the prodrug is administered or the acidic conditions of the stomach, or it can be supplied exogenously.
“Progroup” refers to a type of protecting group that, when used to mask a functional group within an active 2,4-pyrimidinediamine drug to form a promoiety, converts the drug into a prodrug. Progroups are typically attached to the functional group of the drug via bonds that are cleavable under specified conditions of use. Thus, a progroup is that portion of a promoiety that cleaves to release the functional group under the specified conditions of use. As a specific example, an amide promoiety of the formula —NH—C(O)CH3 comprises the progroup —C(O)CH3.
“Pharmaceutically effective amount” and “therapeutically effective amount” refer to an amount of a compound sufficient to treat a specified disorder or disease or one or more of its symptoms and/or to prevent the occurrence of the disease or disorder. In reference to tumorigenic proliferative disorders, a pharmaceutically or therapeutically effective amount comprises an amount sufficient to, among other things, cause the tumor to shrink or decrease the growth rate of the tumor.
“Solvate” refers to a complex formed by combination of solvent molecules with molecules or ions of the solute. The solvent can be an organic compound, an inorganic compound, or a mixture of both. Some examples of solvents include, but are not limited to, methanol, N,N-dimethylformamide, tetrahydrofuran, dimethylsulfoxide, and water.
Unless indicated otherwise, the nomenclature of substituents that are not explicitly defined herein are arrived at by naming the terminal portion of the functionality followed by the adjacent functionality toward the point of attachment. For example, the substituent “arylalkyloxycarbonyl” refers to the group (aryl)-(alkyl)-O—C(O)—.
It is understood that in all substituted groups defined above, polymers arrived at by defining substituents with further substituents to themselves (e.g., substituted aryl having a substituted aryl group as a substituent which is itself substituted with a substituted aryl group, which is further substituted by a substituted aryl group, etc.) are not intended for inclusion herein. In such cases, the maximum number of such substitutions is three. For example, serial substitutions of substituted aryl groups are limited to -substituted aryl-(substituted aryl)-substituted aryl.
Similarly, it is understood that the above definitions are not intended to include impermissible substitution patterns (e.g., methyl substituted with 5 fluoro groups). Such impermissible substitution patterns are easily recognized by a person having ordinary skill in the art.

Those of skill in the art will appreciate that the 2,4-pyrimidinediamine compounds described herein may include functional groups that can be masked with progroups to create prodrugs. Such prodrugs are usually, but need not be, pharmacologically inactive until converted into their active drug form. Indeed, many of the 2,4-pyrimidinediamine compounds described in this invention include promoieties that are hydrolyzable or otherwise cleavable under conditions of use. For example, ester groups commonly undergo acid-catalyzed hydrolysis to yield the parent carboxylic acid when exposed to the acidic conditions of the stomach or base-catalyzed hydrolysis when exposed to the basic conditions of the intestine or blood. Thus, when administered to a subject orally, 2,4-pyrimidinediamine compounds that include ester moieties can be considered prodrugs of their corresponding carboxylic acid, regardless of whether the ester form is pharmacologically active.
The mechanism by which the progroup(s) metabolizes is not critical and can be caused, for example, by hydrolysis under the acidic conditions of the stomach, as described above, and/or by enzymes present in the digestive tract and/or tissues or organs of the body. Indeed, the progroup(s) can be selected to metabolize at a particular site within the body. For example, many esters are cleaved under the acidic conditions found in the stomach. Prodrugs designed to cleave chemically in the stomach to the active 2,4-pyrimidinediamine can employ progroups including such esters. Alternatively, the progroups can be designed to metabolize in the presence of enzymes such as esterases, amidases, lipases, and phosphatases, including ATPases and kinase, etc. Progroups including linkages capable of metabolizing in vivo are well known and include, by way of example and not limitation, ethers, thioethers, silylethers, silylthioethers, esters, thioesters, carbonates, thiocarbonates, carbamates, thiocarbamates, ureas, thioureas, and carboxamides. In some instances, a “precursor” group that is oxidized by oxidative enzymes such as, for example, cytochrome P450 of the liver, to a metabolizable group, can be selected.
In the prodrugs, any available functional moiety can be masked with a progroup to yield a prodrug. Functional groups within the 2,4-pyrimidinediamine compounds that can be masked with progroups for inclusion in a promoiety include, but are not limited to, amines (primary and secondary), hydroxyls, sulfanyls (thiols), and carboxyls. A wide variety of progroups, as well as the resultant promoieties, suitable for masking functional groups in active 2,4-pyrimidinediamine compounds to yield prodrugs are well-known in the art. For example, a hydroxyl functional group can be masked as a sulfonate, ester, or carbonate promoiety, which can be hydrolyzed in vivo to provide the hydroxyl group. An amino functional group can be masked as an amide, carbamate, imine, urea, phosphenyl, phosphoryl, or sulfenyl promoiety, which can be hydrolyzed in vivo to provide the amino group. A carboxyl group can be masked as an ester (including silyl esters and thioesters), amide, or hydrazide promoiety, which can be hydrolyzed in vivo to provide the carboxyl group. Other specific examples of suitable progroups and their respective promoieties will be apparent to those of skill in the art. All of these progroups, alone or in combinations, can be included in the prodrugs.
In some embodiments of the 2,4-pyrimidinediamine compounds and methods of using the compounds, the progroup(s) can be attached to any available primary or secondary amine, including, for example, the N2 nitrogen atom of the 2,4-pyrimidinediamine moiety, the N4 nitrogen atom of the 2,4-pyrimidinediamine moiety, and/or a primary or secondary nitrogen atom included in a substituent on the 2,4-pyrimidinediamine compound.
In particular embodiments of the 2,4-pyrimidinediamine compounds and methods of using the compounds, the prodrugs described herein are 2,4-pyrimidinediamine compounds that are substituted at the N4 nitrogen of the 2,4-pyrimidinediamine moiety with a substituted or unsubstituted nitrogen-containing bicyclic ring that includes at least one progroup at one or more of the following: the nitrogen atom(s) of the bicyclic ring, the N2 nitrogen of the 2,4-pyrimidinediamine moiety, and the N4 nitrogen of the 2,4-pyrimidinediamine moiety.
As noted above, the identity of the progroup is not critical, provided that it can be metabolized under the desired conditions of use, for example, under the acidic conditions found in the stomach and/or by enzymes found in vivo, to yield a biologically active group, e.g., the 2,4-pyrimidinediamines as described herein. Thus, skilled artisans will appreciate that the progroup can comprise virtually any known or later-discovered hydroxyl, amine or thiol protecting group. Non-limiting examples of suitable protecting groups can be found, for example, in Protective Groups in Organic Synthesis, Greene & Wuts, 2nd Ed., John Wiley & Sons, New York, 1991 (especially pages 10-142 (alcohols, 277-308 (thiols) and 309-405 (amines) the disclosure of which is incorporated herein by reference).
Additionally, the identity of the progroup(s) can also be selected so as to impart the prodrug with desirable characteristics. For example, lipophilic groups can be used to decrease water solubility and hydrophilic groups can be used to increase water solubility. In this way, prodrugs specifically tailored for selected modes of administration can be obtained. The progroup can also be designed to impart the prodrug with other properties, such as, for example, improved passive intestinal absorption, improved transport-mediated intestinal absorption, protection against fast metabolism (slow-release prodrugs), tissue-selective delivery, passive enrichment in target tissues, and targeting-specific transporters. Groups capable of imparting prodrugs with these characteristics are well-known and are described, for example, in Ettmayer et al., 2004, J. Med. Chem. 47(10):2393-2404, the disclosure of which is incorporated by reference. All of the various groups described in these references can be utilized in the prodrugs described herein.
As noted above, progroup(s) may also be selected to increase the water solubility of the prodrug as compared to the active drug. Thus, the progroup(s) may include or can be a group(s) suitable for imparting drug molecules with improved water solubility. Such groups are well-known and include, by way of example and not limitation, hydrophilic groups such as alkyl, aryl, and arylalkyl, or cycloheteroalkyl groups substituted with one or more of an amine, alcohol, a carboxylic acid, a phosphorous acid, a sulfoxide, a sugar, an amino acid, a thiol, a polyol, an ether, a thioether, and a quaternary amine salt.
Suitability of any particular progroup for a desired mode of administration can be confirmed in biochemical assays. For example, if a prodrug is to be administered by injection into a particular tissue or organ and the identities of the various enzyme(s) expressed in the tissue or organ are known, the particular prodrug can be tested for metabolism in biochemical assays with the isolated enzyme(s). Alternatively, the particular prodrug can be tested for metabolism to the active 2,4-pyrimidinediamine compound with tissue and/or organ extracts. Using tissue and/or organ extracts can be of particular convenience when the identity(ies) of the enzymes expressed in the target tissues or organs are unknown or in instances when the isolated enzymes are not conveniently available. Skilled artisans will be able to readily select progroups having metabolic properties (such as kinetics) suitable for particular applications using such in vitro tests. Of course, specific prodrugs could also be tested for suitable metabolism in vitro animal models.
Numerous references teach the use and synthesis of prodrugs, including, for example, Ettmayer et al., supra and Bungaard et al., (1989) J. Med. Chem. 32(12): 2503-2507. Additionally, the preparation and use of prodrugs of 2,4-pyrimidinediamines is specifically taught in U.S. Provisional Patent Application 60/654,620, filed Feb. 18, 2005, entitled “Pyrimidinediamine Prodrugs and their Uses,” the disclosure of which is hereby incorporated by reference in its entirety.
One of ordinary skill in the art will appreciate that many of the compounds and prodrugs thereof, as well as the various compound species specifically described and/or illustrated herein, may exhibit the phenomena of tautomerism, conformational isomerism, geometric isomerism, and/or optical isomerism. For example, the compounds and prodrugs of the invention may include one or more chiral centers and/or double bonds and as a consequence may exist as stereoisomers, such as double-bond isomers (i.e., geometric isomers), enantiomers, diasteromers, and mixtures thereof, such as racemic mixtures. As another example, the compounds and prodrugs of the invention may exist in several tautomeric forms, including the enol form, the keto form, and mixtures thereof. As the various compound names, formulae and compound drawings within the specification and claims can represent only one of the possible tautomeric, conformational isomeric, optical isomeric, or geometric isomeric forms, it should be understood that the invention encompasses any tautomeric, conformational isomeric, optical isomeric, and/or geometric isomeric forms of the compounds or prodrugs having one or more of the utilities described herein, as well as mixtures of these various different isomeric forms. In cases of limited rotation around the 2,4-pyrimidinediamine core structure, atropisomers are also possible and are also specifically included in the compounds of the invention. It is intended that the compounds encompassed herein are, with the exception of forms of isomerism, chemically stable and able to be isolated.
Depending upon the nature of the various substituents, the 2,4-pyrimidinediamine compounds and prodrugs of the invention can be in the form of salts. Such salts include salts suitable for pharmaceutical uses (“pharmaceutically-acceptable salts”), salts suitable for veterinary uses, etc. Such salts can be derived from acids or bases, as is well-known in the art.
In one embodiment, the salt is a pharmaceutically acceptable salt. Generally, pharmaceutically acceptable salts are those salts that retain substantially one or more of the desired pharmacological activities of the parent compound and which are suitable for administration to humans. Pharmaceutically acceptable salts include acid addition salts formed with inorganic acids or organic acids. Inorganic acids suitable for forming pharmaceutically acceptable acid addition salts include, by way of example and not limitation, hydrohalide acids (e.g., hydrochloric acid, hydrobromic acid, hydroiodic acid, etc.), sulfuric acid, nitric acid, phosphoric acid, and the like. Organic acids suitable for forming pharmaceutically acceptable acid addition salts include, by way of example and not limitation, acetic acid, trifluoroacetic acid, propionic acid, hexanoic acid, cyclopentanepropionic acid, glycolic acid, oxalic acid, pyruvic acid, lactic acid, malonic acid, succinic acid, malic acid, maleic acid, fumaric acid, tartaric acid, citric acid, palmitic acid, benzoic acid, 3-(4-hydroxybenzoyl)benzoic acid, cinnamic acid, mandelic acid, alkylsulfonic acids (e.g., methanesulfonic acid, ethanesulfonic acid, 1,2-ethane-disulfonic acid, 2-hydroxyethanesulfonic acid, etc.), arylsulfonic acids (e.g., benzenesulfonic acid, 4-chlorobenzenesulfonic acid, 2-naphthalenesulfonic acid, 4-toluenesulfonic acid, camphorsulfonic acid, etc.), 4-methylbicyclo[2.2.2]-oct-2-ene-1-carboxylic acid, glucoheptonic acid, 3-phenylpropionic acid, trimethylacetic acid, tertiary butylacetic acid, lauryl sulfuric acid, gluconic acid, glutamic acid, hydroxynaphthoic acid, salicylic acid, stearic acid, muconic acid, and the like.
Pharmaceutically acceptable salts also include salts formed when an acidic proton present in the parent compound is either replaced by a metal ion (e.g., an alkali metal ion, an alkaline earth metal ion, or an aluminum ion) or coordinates with an organic base (e.g., ethanolamine, diethanolamine, triethanolamine, N-methylglucamine, morpholine, piperidine, dimethylamine, diethylamine, triethylamine, and ammonia).
The 2,4-pyrimidinediamine compounds and prodrugs thereof, as well as the salts thereof, may also be in the form of hydrates, solvates, and N-oxides, as is well-known in the art.

D. Methods of the Invention
The present invention provides 2,4-pyrimidinediamine compounds and prodrugs thereof, as described herein, for use in therapy for the conditions described herein. The present invention further provides use of the compounds of the present invention in the manufacture of a medicament for the treatment of conditions in which targeting of the JAK pathway or inhibition of JAK kinases, particularly JAK3, are therapeutically useful. These include conditions where the function of lymphocytes, macrophages, or mast cells is involved. Conditions in which targeting of the JAK pathway or inhibition of the JAK kinases, particularly JAK3, are therapeutically useful include leukemia, lymphoma, transplant rejection (e.g., pancreas islet transplant rejection), bone marrow transplant applications (e.g., graft-versus-host disease)), autoimmune diseases (e.g., rheumatoid arthritis, etc.), inflammation (e.g., asthma, etc.) and other conditions as described in greater detail herein.
As noted previously, numerous conditions can be treated using the 2,4-substituted pyrimidinediamine compounds, prodrugs thereof, and methods of treatment as described herein. As used herein, “Treating” or “treatment” of a disease in a patient refers to (1) preventing the disease from occurring in a patient that is predisposed or does not yet display symptoms of the disease; (2) inhibiting the disease or arresting its development; or (3) ameliorating or causing regression of the disease. As well understood in the art, “treatment” is an approach for obtaining beneficial or desired results, including clinical results. For the purposes of this invention, beneficial or desired results can include one or more, but are not limited to, alleviation or amelioration of one or more symptoms, diminishment of extent of a condition, including a disease, stabilized (i.e., not worsening) state of a condition, including diseases, preventing spread of disease, delay or slowing of condition, including disease, progression, amelioration or palliation of the condition, including disease, state, and remission (whether partial or total), whether detectable or undetectable. Preferred are compounds that are potent and can be administered locally at very low doses, thus minimizing systemic adverse effects.
The compounds described herein are potent and selective inhibitors of JAK kinases and are particularly selective for cytokine signaling pathways containing JAK3. As a consequence of this activity, the compounds can be used in a variety of in vitro, in vivo, and ex vivo contexts to regulate or inhibit JAK kinase activity, signaling cascades in which JAK kinases play a role, and the biological responses effected by such signaling cascades. For example, in one embodiment, the compounds can be used to inhibit JAK kinase, either in vitro or in vivo, in virtually any cell type expressing the JAK kinase, such as in hematopoietic cells in which, for example, JAK3 is predominantly expressed. They may also be used to regulate signal transduction cascades in which JAK kinases, particularly JAK3, play a role. Such JAK-dependent signal transduction cascades include, but are not limited to, the signaling cascades of cytokine receptors that involve the common gamma chain, such as, for example, the IL-4, IL-7, IL-5, IL-9, IL-15 and IL-21, or IL-2, IL-4, IL-7, IL-9, IL-15, and IL-21 receptor signaling cascades. The compounds may also be used in vitro or in vivo to regulate, and in particular to inhibit, cellular or biological responses affected by such JAK-dependent signal transduction cascades. Such cellular or biological responses include, but are not limited to, IL-4/ramos CD23 upregulation and IL-2 mediated T-cell proliferation. Importantly, the compounds can be used to inhibit JAK kinases in vivo as a therapeutic approach towards the treatment or prevention of diseases mediated, either wholly or in part, by a JAK kinase activity (referred to herein as “JAK kinase mediated diseases”). Non-limiting examples of JAK kinase mediated diseases that can be treated or prevented with the compounds include, but are not limited to, the following: allergies; asthma; autoimmune diseases such as transplant rejection (e.g., kidney, heart, lung, liver, pancreas, skin; host versus graft reaction (HVGR), and graft versus host reaction (GVHR)), rheumatoid arthritis, and amyotrophic lateral sclerosis; T-cell mediated autoimmune diseases such as multiple sclerosis, psoriasis, and Sjogren's syndrome; Type II inflammatory diseases such as vascular inflammation (including vasculitis, arteritis, atherosclerosis, and coronary artery disease); diseases of the central nervous system such as stroke; pulmonary diseases such as bronchitis obliteraus and primary pulmonary hypertension; solid, delayed Type IV hypersensitivity reactions; and hematologic malignancies such as leukemia and lymphomas.
In one embodiment, this invention provides a method of inhibiting an activity of a JAK kinase, comprising contacting the JAK kinase with an amount of a compound effective to inhibit an activity of the JAK kinase wherein the compound is a compound of formula I:

In another embodiment, this invention provides a method of inhibiting an activity of a JAK kinase, comprising contacting the JAK kinase with an amount of a compound effective to inhibit an activity of the JAK kinase, wherein the compound is selected from the compounds of this invention, as described herein. In certain embodiments of the methods described herein, the method is carried out in vivo.
In another embodiment, this invention provides a method of inhibiting an activity of a JAK kinase, comprising contacting in vitro a JAK3 kinase with an amount of a compound effective to inhibit an activity of the JAK kinase, wherein the compound is selected from the compounds of this invention, as described herein.
In a specific embodiment, the compounds can be used to treat and/or prevent rejection in organ and/or tissue transplant recipients (i.e., treat and/or prevent allograft rejection). Allografts can be rejected through either a cell-mediated or humoral immune reaction of the recipient against transplant (histocompability) antigens present on the membranes of the donor's cells. The strongest antigens are governed by a complex of genetic loci termed human leukocyte group A (HLA) antigens. Together with the ABO blood groups antigens, they are the chief transplantation antigens detectable in humans.
Rejection following transplantation can generally be broken into three categories: hyperacute, occurring hours to days following transplantation; acute, occurring days to months following transplantation; and chronic, occurring months to years following transplantation.
Hyperacute rejection is caused mainly by the production of host antibodies that attack the graft tissue. In a hyperacute rejection reaction, antibodies are observed in the transplant vascular very soon after transplantation. Shortly thereafter, vascular clotting occurs, leading to ischemia, eventual necrosis and death. The graft infarction is unresponsive to known immunosuppressive therapies. Because HLA antigens can be identified in vitro, pre-transplant screening is used to significantly reduce hyperacute rejection. As a consequence of this screening, hyperacute rejection is relatively uncommon today.
Acute rejection is thought to be mediated by the accumulation of antigen specific cells in the graft tissue. The T-cell-mediated immune reaction against these antigens (i.e., HVGR or GVHR) is the principle mechanism of acute rejection. Accumulation of these cells leads to damage of the graft tissue. It is believed that both CD4+ helper T-cells and CD8+ cytotoxic T-cells are involved in the process and that the antigen is presented by donor and host dendritic cells. The CD4+ helper T-cells help recruit other effector cells, such as macrophages and eosinophils, to the graft. Accessing T-cell activation signal transduction cascades (for example, CD28, CD40L, and CD2 cascades) are also involved.
The cell-mediated acute rejection can be reversed in many cases by intensifying immunotherapy. After successful reversal, severely damaged elements of the graft heal by fibrosis and the remainder of the graft appears normal. After resolution of acute rejection, dosages of immunosuppressive drugs can be reduced to very low levels.
Chronic rejection, which is a particular problem in renal transplants, often progresses insidiously despite increased immunosuppressive therapy. It is thought to be due, in large part, to cell-mediated Type IV hypersensitivity. The pathologic profile differs from that of acute rejection. The arterial endothelium is primarily involved with extensive proliferation that may gradually occlude the vessel lumen, leading to ischemia, fibrosis, a thickened intima, and atherosclerotic changes. Chronic rejection is mainly due to a progressive obliteration of graft vasculature and resembles a slow, vasculitis process.
In Type IV hypersensitivity, CD8 cytotoxic T-cells and CD4 helper T cells recognize either intracellular or extracellular synthesized antigen when it is complexed, respectively, with either Class I or Class II MHC molecules. Macrophages function as antigen-presenting cells and release IL-1, which promotes proliferation of helper T-cells. Helper T-cells release interferon gamma and IL-2, which together regulate delayed hyperactivity reactions mediated by macrophage activation and immunity mediated by T cells. In the case of organ transplant, the cytotoxic T-cells destroy the graft cells on contact.
Since JAK kinases play a critical role in the activation of T-cells, the 2,4-pyrimidinediamine compounds described herein can be used to treat and/or prevent many aspects of transplant rejection, and are particularly useful in the treatment and/or prevention of rejection reactions that are mediated, at least in part, by T-cells, such as HVGR or GVHR. The 2,4-pyrimidinediamine compounds can also be used to treat and/or prevent chronic rejection in transplant recipients and, in particular, in renal transplant recipients. The compound can also be administered to a tissue or an organ prior to transplanting the tissue or organ in the transplant recipient.
In another embodiment, this invention provides a method of treating a T-cell mediated autoimmune disease, comprising administering to a patient suffering from such an autoimmune disease an amount of a compound effective to treat the autoimmune disease wherein the compound is selected from the compounds of the invention, as described herein. In certain embodiments of the methods the autoimmune disease is multiple sclerosis (MS), psoriasis, or Sjogren's syndrome.
Therapy using the 2,4-pyrimidinediamine compounds described herein can be applied alone, or it can be applied in combination with or adjunctive to other common immunosuppressive therapies, such as, for example, the following: mercaptopurine; corticosteroids such as prednisone; methylprednisolone and prednisolone; alkylating agents such as cyclophosphamide; calcineurin inhibitors such as cyclosporine, sirolimus, and tacrolimus; inhibitors of inosine monophosphate dehydrogenase (IMPDH) such as mycophenolate, mycophenolate mofetil, and azathioprine; and agents designed to suppress cellular immunity while leaving the recipient's humoral immunologic response intact, including various antibodies (for example, antilymphocyte globulin (ALG), antithymocyte globulin (ATG), monoclonal anti-T-cell antibodies (OKT3)) and irradiation. These various agents can be used in accordance with their standard or common dosages, as specified in the prescribing information accompanying commercially available forms of the drugs (see also: the prescribing information in the 2006 Edition of The Physician's Desk Reference), the disclosures of which are incorporated herein by reference. Azathioprine is currently available from Salix Pharmaceuticals, Inc., under the brand name AZASAN; mercaptopurine is currently available from Gate Pharmaceuticals, Inc., under the brand name PURINETHOL; prednisone and prednisolone are currently available from Roxane Laboratories, Inc.; Methyl prednisolone is currently available from Pfizer; sirolimus (rapamycin) is currently available from Wyeth-Ayerst under the brand name RAPAMUNE; tacrolimus is currently available from Fujisawa under the brand name PROGRAF; cyclosporine is current available from Novartis under the brand name SANDIMMUNE and from Abbott under the brand name GENGRAF; IMPDH inhibitors such as mycophenolate mofetil and mycophenolic acid are currently available from Roche under the brand name CELLCEPT and from Novartis under the brand name MYFORTIC; azathioprine is currently available from Glaxo Smith Kline under the brand name IMURAN; and antibodies are currently available from Ortho Biotech under the brand name ORTHOCLONE, from Novartis under the brand name SIMULECT (basiliximab), and from Roche under the brand name ZENAPAX (daclizumab).
In another embodiment, the 2,4-pyrimidinediamine compounds could be administered either in combination or adjunctively with an inhibitor of a Syk kinase. Syk kinase is a tyrosine kinase known to play a critical role in Fcγ receptor signaling, as well as in other signaling cascades, such as those involving B-Cell receptor signaling (Tumer et al., (2000), Immunology Today 21:148-154) and integrins beta(1), beta (2), and beta (3) in neutrophils (Mocsavi et al., (2002), Immunity 16:547-558). For example, Syk kinase plays a pivotal role in high affinity IgE receptor signaling in mast cells that leads to activation and subsequent release of multiple chemical mediators that trigger allergic attacks. However, unlike the JAK kinases, which help regulate the pathways involved in delayed or cell-mediated Type IV hypersensitivity reactions, Syk kinase helps regulate the pathways involved in immediate IgE-mediated, Type I hypersensitivity reactions. Certain compounds that affect the Syk pathway may or may not also affect the JAK pathways.
Suitable Syk inhibitory compounds are described, for example, in Ser. No. 10/355,543 filed Jan. 31, 2003 (publication no. 2004/0029902); WO 03/063794; Ser.

The 2,4-pyrimidinediamine compounds described herein are cytokine moderators of IL-4 signaling. As a consequence, the 2,4-pyrimidinediamine compounds could slow the response of Type I hypersensitivity reactions. Thus, in a specific embodiment, the 2,4-pyrimidinediamine compounds could be used to treat such reactions and, therefore, the diseases associated with, mediated by, or caused by such hypersensitivity reactions (for example, allergies), prophylactically. For example, an allergy sufferer could take one or more of the JAK selective compounds described herein prior to expected exposure to allergens to delay the onset or progress of, or eliminate altogether, an allergic response.

Active compounds of the invention typically inhibit the JAK/Stat pathway. The activity of a specified compound as an inhibitor of a JAK kinase can be assessed in vitro or in vivo. In some embodiments, the activity of a specified compound can be tested in a cellular assay. Suitable assays include assays that determine inhibition of either the phosphorylation activity or ATPase activity of a JAK kinase. Thus, a compound is said to inhibit an activity of a JAK kinase if it inhibits the phosphorylation or ATPase activity of a JAK kinase with an IC50 of about 20 μM or less.
“Cell proliferative disorder” refers to a disorder characterized by abnormal proliferation of cells. A proliferative disorder does not imply any limitation with respect to the rate of cell growth, but merely indicates loss of normal controls that affect growth and cell division. Thus, in some embodiments, cells of a proliferative disorder can have the same cell division rates as normal cells but do not respond to signals that limit such growth. Within the ambit of “cell proliferative disorder” is neoplasm or tumor, which is an abnormal growth of tissue. Cancer refers to any of various malignant neoplasms characterized by the proliferation of cells that have the capability to invade surrounding tissue and/or metastasize to new colonization sites.
“Hematopoietic neoplasm” refers to a cell proliferative disorder arising from cells of the hematopoietic lineage. Generally, hematopoiesis is the physiological process whereby undifferentiated cells or stem cells develop into various cells found in the peripheral blood. In the initial phase of development, hematopoietic stem cells, typically found in the bone marrow, undergo a series of cell divisions to form multipotent progenitor cells that commit to two main developmental pathways: the lymphoid lineage and the myeloid lineage. The committed progenitor cells of the myeloid lineage differentiate into three major sub-branches comprised of the erythroid, megakaryocyte, and granulocyte/monocyte developmental pathways. An additional pathway leads to formation of dendritic cells, which are involved in antigen presentation. The erythroid lineage gives rise to red blood cells while the megakaryocytic lineage gives rise to blood platelets. Committed cells of the granulocyte/monocyte lineage split into granulocyte or monocyte developmental pathways, the former pathway leading to formation of neutrophils, eosinophils, and basophils and the latter pathway giving rise to blood monocytes and macrophages.
Committed progenitor cells of the lymphoid lineage develop into the B cell pathway, T cell pathway, or the non-T/B cell pathway. Similar to the myeloid lineage, an additional lymphoid pathway appears to give rise to dendritic cells involved in antigen presentation. The B cell progenitor cell develops into a precursor B cell (pre-B), which differentiates into B cells responsible for producing immunoglobulins. Progenitor cells of the T cell lineage differentiate into precursor T cells (pre-T) that, based on the influence of certain cytokines, develop into cytotoxic or helper/suppressor T cells involved in cell mediated immunity. Non-T/B cell pathway leads to generation of natural killer (NK) cells. Neoplasms of hematopoietic cells can involve cells of any phase of hematopoiesis, including hematopoietic stem cells, multipotent progenitor cells, oligopotent committed progenitor cells, precursor cells, and mature differentiated cells. The categories of hematopoietic neoplasms can generally follow the descriptions and diagnostic criteria employed by those of skill in the art (see, e.g., International Classification of Disease and Related Health Problems (ICD 10), World Health Organization (2003)). Hematopoietic neoplasms can also be characterized based on the molecular features, such as cell surface markers and gene expression profiles, cell phenotype exhibited by the aberrant cells, and/or chromosomal aberrations (e.g., deletions, translocations, insertions, etc.) characteristic of certain hematopoietic neoplasms, such as the Philadelphia chromosome found in chronic myelogenous leukemia. Other classifications include National Cancer Institute Working Formulation (Cancer, 1982, 49:2112-2135) and Revised European-American Lymphoma Classification (REAL).
“Lymphoid neoplasm” refers a proliferative disorder involving cells of the lymphoid lineage of hematopoiesis. Lymphoid neoplasms can arise from hematopoietic stem cells as well as lymphoid committed progenitor cells, precursor cells, and terminally differentiated cells. These neoplasms can be subdivided based on the phenotypic attributes of the aberrant cells or the differentiated state from which the abnormal cells arise. Subdivisions include, among others, B cell neoplasms, T cell neoplasms, NK cell neoplasms, and Hodgkin's lymphoma.
“Myeloid neoplasm” refers to proliferative disorder of cells of the myeloid lineage of hematopoiesis. Neoplasms can arise from hematopoietic stem cells, myeloid committed progenitor cells, precursor cells, and terminally differentiated cells. Myeloid neoplasms can be subdivided based on the phenotypic attributes of the aberrant cells or the differentiated state from which the abnormal cells arise. Subdivisions include, among others, myeloproliferative diseases, myelodysplastic/myeloproliferative diseases, myelodysplastic syndromes, acute myeloid leukemia, and acute biphenotypic leukemia.
Generally cell proliferative disorders treatable with the compounds disclosed herein relate to any disorder characterized by aberrant cell proliferation. These include various tumors and cancers, benign or malignant, metastatic or non-metastatic. Specific properties of cancers, such as tissue invasiveness or metastasis, can be targeted using the methods described herein. Cell proliferative disorders include a variety of cancers, including, among others, breast cancer, ovarian cancer, renal cancer, gastrointestinal cancer, kidney cancer, bladder cancer, pancreatic cancer, lung squamous carcinoma, and adenocarcinoma.
In some embodiments, the cell proliferative disorder treated is a hematopoietic neoplasm, which is aberrant growth of cells of the hematopoietic system. Hematopoietic malignancies can have its origins in pluripotent stem cells, multipotent progenitor cells, oligopotent committed progenitor cells, precursor cells, and terminally differentiated cells involved in hematopoiesis. Some hematological malignancies are believed to arise from hematopoietic stem cells, which have the ability for self renewal. For instance, cells capable of developing specific subtypes of acute myeloid leukemia (AML) upon transplantation display the cell surface markers of hematopoietic stem cells, implicating hematopoietic stem cells as the source of leukemic cells. Blast cells that do not have a cell marker characteristic of hematopoietic stem cells appear to be incapable of establishing tumors upon transplantation (Blaire et al., 1997, Blood 89:3104-3112). The stem cell origin of certain hematological malignancies also finds support in the observation that specific chromosomal abnormalities associated with particular types of leukemia can be found in normal cells of hematopoietic lineage as well as leukemic blast cells. For instance, the reciprocal translocation t(9q34; 22q11) associated with approximately 95% of chronic myelogenous leukemia appears to be present in cells of the myeloid, erythroid, and lymphoid lineage, suggesting that the chromosomal aberration originates in hematopoietic stem cells. A subgroup of cells in certain types of CML displays the cell marker phenotype of hematopoietic stem cells.
Although hematopoietic neoplasms often originate from stem cells, committed progenitor cells or more terminally differentiated cells of a developmental lineage can also be the source of some leukemias. For example, forced expression of the fusion protein Bcr/Abl (associated with chronic myelogenous leukemia) in common myeloid progenitor or granulocyte/macrophage progenitor cells produces a leukemic-like condition. Moreover, some chromosomal aberrations associated with subtypes of leukemia are not found in the cell population with a marker phenotype of hematopoietic stem cells, but are found in a cell population displaying markers of a more differentiated state of the hematopoietic pathway (Turhan et al., 1995, Blood 85:2154-2161). Thus, while committed progenitor cells and other differentiated cells may have only a limited potential for cell division, leukemic cells may have acquired the ability to grow unregulated, in some instances mimicking the self-renewal characteristics of hematopoietic stem cells (Passegue et al., Proc. Natl. Acad. Sci. USA, 2003, 100:11842-9).
In some embodiments, the hematopoietic neoplasm treated is a lymphoid neoplasm, where the abnormal cells are derived from and/or display the characteristic phenotype of cells of the lymphoid lineage. Lymphoid neoplasms can be subdivided into B-cell neoplasms, T and NK-cell neoplasms, and Hodgkin's lymphoma. B-cell neoplasms can be further subdivided into precursor B-cell neoplasm and mature/peripheral B-cell neoplasm. Exemplary B-cell neoplasms are precursor B-lymphoblastic leukemia/lymphoma (precursor B-cell acute lymphoblastic leukemia) while exemplary mature/peripheral B-cell neoplasms are B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma, B-cell prolymphocytic leukemia, lymphoplamacytic lymphoma, splenic marginal zone B-cell lymphoma, hairy cell leukemia, plasma cell myeloma/plasmacytoma, extranodal marginal zone B-cell lymphoma of MALT type, nodal marginal zone B-cell lymphoma, follicular lymphoma, mantle-cell lymphoma, diffuse large B-cell lymphoma, mediastinal large B-cell lymphoma, primary effusion lymphoma, and Burkitt's lymphoma/Burkitt cell leukemia.

In various embodiments, any of the lymphoid neoplasms that are associated with aberrant JAK activity can be treated with the JAK inhibitory compounds.
In some embodiments, the hematopoietic neoplasm treated is a myeloid neoplasm. This group comprises a large class of cell proliferative disorders involving or displaying the characteristic phenotype of the cells of the myeloid lineage. Myeloid neoplasms can be subdivided into myeloproliferative diseases, myelodysplastic/myeloproliferative diseases, myelodysplastic syndromes, and acute myeloid leukemias. Exemplary myeloproliferative diseases are chronic myelogenous leukemia (e.g., Philadelphia chromosome positive (t(9; 22)(qq34;q 11)), chronic neutrophilic leukemia, chronic eosinophilic leukemia/hypereosinophilic syndrome, chronic idiopathic myelofibrosis, polycythemia vera, and essential thrombocythemia. Exemplary myelodysplastic/myeloproliferative diseases are chronic myelomonocytic leukemia, atypical chronic myelogenous leukemia, and juvenile myelomonocytic leukemia. Exemplary myelodysplastic syndromes are refractory anemia, with ringed sideroblasts and without ringed sideroblasts, refractory cytopenia (myelodysplastic syndrome) with multilineage dysplasia, refractory anemia (myelodysplastic syndrome) with excess blasts, 5q-syndrome, and myelodysplastic syndrome. In various embodiments, any of the myeloid neoplasms that are associated with aberrant JAK activity can be treated with the JAK inhibitory compounds.
In some embodiments, the JAK inhibitory compounds can be used to treat Acute myeloid leukemias (AML), which represent a large class of myeloid neoplasms having its own subdivision of disorders. These subdivisions include, among others, AMLs with recurrent cytogenetic translocations, AML with multilineage dysplasia, and other AML not otherwise categorized. Exemplary AMLs with recurrent cytogenetic translocations include, among others, AML with t(8; 21)(q22;q22), AML1 (CBF-alpha)/ETO, Acute promyelocytic leukemia (AML with t(15; 17)(q22;q11-12) and variants, PML/RAR-alpha), AML with abnormal bone marrow eosinophils (inv(16)(p13q22) or t(16; 16)(p13;q11), CBFb/MYH11X), and AML with 11q23 (MLL) abnormalities. Exemplary AML with multilineage dysplasia are those that are associated with or without prior myelodysplastic syndrome. Other acute myeloid leukemias not classified within any definable group include, AML minimally differentiated, AML without maturation, AML with maturation, Acute myelomonocytic leukemia, Acute monocytic leukemia, Acute erythroid leukemia, Acute megakaryocytic leukemia, Acute basophilic leukemia, and Acute panmyelosis with myelofibrosis.
One means of assaying for such inhibition is detection of the effect of the 2,4-pyrimidinediamine compounds on the upregulation of downstream gene products. In the Ramos/IL4 assay, B-cells are stimulated with the cytokine Interleukin-4 (IL-4) leading to the activation of the JAK/Stat pathway through phosphorylation of the JAK family kinases, JAK1 and JAK3, which in turn phosphorylate and activate the transcription factor Stat-6. One of the genes upregulated by activated Stat-6 is the low affinity IgE receptor, CD23. To study the effect of inhibitors (e.g., the 2,4-substituted pyrimindinediamine compounds described herein) on the JAK1 and JAK3 kinases, human Ramos B cells are stimulated with human IL-4. 20 to 24 hours post stimulation, cells are stained for upregulation of CD23 and analyzed using flow cytometry (FACS). A reduction of the amount of CD23 present compared to control conditions indicates the test compound actively inhibits the JAK kinase pathway. An exemplary assay of this type is described in greater detail in Example 2.
The activity of the active compounds of the invention may further be characterized by assaying the effect of the 2,4-pyrimidinediamine compounds described herein on the proliferative response of primary human T-cells. In this assay, primary human T-cells derived from peripheral blood and pre-activated through stimulation of the T-cell receptor and CD28, proliferate in culture in response to the cytokine Interleukin-2 (IL-2). This proliferative response is dependent on the activation of JAK1 and JAK3 tyrosine kinases, which phosphorylate and activate the transcription factor Stat-5. The primary human T-cells are incubated with the 2,4-pyrimidinediamine compounds in the presence of IL-2 for 72 hours, and at the assay endpoint intracellular ATP concentrations are measured to assess cell viability. A reduction in cell proliferation compared to control conditions is indicative of inhibition of the JAK kinase pathway.
The activity of the compounds of the invention may additionally be characterized by assaying the effect of the 2,4-pyrimidinediamine compounds described herein on A549 lung epithelial cells and U937 cells. A549 lung epithelial cells and U937 cells up-regulate ICAM-1 (CD54) surface expression in response to a variety of different stimuli. Therefore, using ICAM-1 expression as readout, test compound effects on different signaling pathways can be assessed in the same cell type. Stimulation with IL-1β through the IL-1β receptor activates the TRAF6/NFκB pathway resulting in up-regulation of ICAM-1. IFNγ induces ICAM-1 up-regulation through activation of the JAK1/JAK2 pathway. The up-regulation of ICAM-1 can be quantified by flow cytometry across a compound dose curve and EC50 values are calculated.
Active compounds as described herein generally inhibit the JAK kinase pathway with an IC50 in the range of about 1 mM or less, as measured in the assays described herein. Of course, skilled artisans will appreciate that compounds which exhibit lower IC50s, (on the order, for example, of 100 μM, 75 μM, 50 μM, 40 μM, 30 μM, 20 μM, 15 μM, 10 μM, 5 μM, 1 μM, 500 nM, 100 nM, 10 nM, 1 nM, or even lower) can be particularly useful in therapeutic applications. In instances where activity specific to a particular cell type is desired, the compound can be assayed for activity with the desired cell type and counter-screened for a lack of activity against other cell types. The desired degree of “inactivity” in such counter screens, or the desired ratio of activity vs. inactivity, may vary for different situations and can be selected by the user.
The 2,4-pyrimidinediamine active compounds also typically inhibit IL-4 stimulated expression of CD23 in B-cells with an IC50 in the range of about 20 μM or less, typically in the range of about 10 μM, 1 μM, 500 nM, 100 nM, 10 nM, 1 nM, or even lower. A suitable assay that can be used is the assay described in Example 2, “Assay for Ramos B-Cell Line Stimulated with IL-4.” In certain embodiments, the active 2,4-pyrimidinediamine compounds have an IC50 of less than or equal to 5 μM, greater than 5 μM but less than 20 μM, greater than 20 μM, or greater than 20 μM but less than 50 μM in the assay described in Example 2.
Additionally, the 2,4-pyrimidinediamine active compounds typically inhibit an activity of human primary T-cells with an IC50 in the range of about 20 μM or less, typically in the range of about 10 μM, 1 μM, 500 nM, 100 nM, 10 nM, 1 nM, or even lower. The IC50 against human primary T-cells can be determined in a standard in vitro assay with isolated human primary T-cells. A suitable assay that can be used is the assay described above, “Primary Human T-cell Proliferation Assay Stimulated with IL-2.” In preferred embodiments, the active 2,4-pyrimidinediamine compounds have an IC50 of less than or equal to 5 μM, greater than 5 μM but less than 20 μM, greater than 20 μM, or greater than 20 μM but less than 50 μM in the assay described above.
The 2,4-pyrimidinediamine active compounds also typically inhibit expression of ICAM1 (CD54) induced by IFNγ exposure in U937 or A549 cells with an IC50 in the range of about 20 μM or less, typically in the range of about 10 μM, 1 μM, 500 nM, 100 nM, 10 nM, 1 nM, or even lower. The IC50 against expression of ICAM (CD54) in IFNγ stimulated cells can be determined in a functional cellular assay with an isolated A549 or U937 cell line. The active 2,4-pyrimidinediamine compounds typically have an IC50 of less than or equal to 20 μM, greater than 20 μM, or greater than 20 μM but less than 50 μM in the assay.

The invention also relates to methods for manufacturing compositions including 2,4-pyrimidinediamine compounds in a form that is suitable for topical administration.
According to the present invention, 2,4-pyrimidinediamine compounds can also be delivered by any of a variety of inhalation devices and methods known in the art, including, for example: U.S. Pat. Nos. 6,241,969; 6,060,069; 6,238,647; 6,335,316; 5,364,838; 5,672,581; WO96/32149; WO95/24183; U.S. Pat. Nos. 5,654,007; 5,404,871; 5,672,581; 5,743,250; 5,419,315; 5,558,085; WO98/33480; U.S. Pat. Nos. 5,364,833; 5,320,094; 5,780,014; 5,658,878; 5,518,998; 5,506,203; 5,661,130; 5,655,523; 5,645,051; 5,622,166; 5,577,497; 5,492,112; 5,327,883; 5,277,195; U.S. Pat. App. No. 20010041190; U.S. Pat. App. No. 20020006901; and U.S. Pat. App. No. 20020034477.
Included among the devices which can be used to administer particular examples of the 2,4-pyrimidinediamine compounds are those well-known in the art, such as metered dose inhalers, liquid nebulizers, dry powder inhalers, sprayers, thermal vaporizers, and the like. Other suitable technology for administration of particular 2,4-pyrimidinediamine compounds includes electrohydrodynamic aerosolizers.
In addition, the inhalation device is preferably practical, in the sense of being easy to use, small enough to carry conveniently, capable of providing multiple doses, and durable. Some specific examples of commercially available inhalation devices are Turbohaler (Astra, Wilmington, Del.), Rotahaler (Glaxo, Research Triangle Park, N.C.), Diskus (Glaxo, Research Triangle Park, N.C.), the Ultravent nebulizer (Mallinckrodt), the Acorn II nebulizer (Marquest Medical Products, Totowa, N.J.) the Ventolin metered dose inhaler (Glaxo, Research Triangle Park, N.C.), and the like. In one embodiment, 2,4-pyrimidinediamine compounds can be delivered by a dry powder inhaler or a sprayer.
As those skilled in the art will recognize, the formulation of 2,4-pyrimidinediamine compounds, the quantity of the formulation delivered, and the duration of administration of a single dose depend on the type of inhalation device employed as well as other factors. For some aerosol delivery systems, such as nebulizers, the frequency of administration and length of time for which the system is activated will depend mainly on the concentration of 2,4-pyrimidinediamine compounds in the aerosol. For example, shorter periods of administration can be used at higher concentrations of 2,4-pyrimidinediamine compounds in the nebulizer solution. Devices such as metered dose inhalers can produce higher aerosol concentrations and can be operated for shorter periods to deliver the desired amount of 2,4-pyrimidinediamine compounds in some embodiments. Devices such as dry powder inhalers deliver active agent until a given charge of agent is expelled from the device. In this type of inhaler, the amount of 2,4-pyrimidinediamine compounds in a given quantity of the powder determines the dose delivered in a single administration. The formulation of 2,4-pyrimidinediamine is selected to yield the desired particle size in the chosen inhalation device.
Formulations of 2,4-pyrimidinediamine compounds for administration from a dry powder inhaler may typically include a finely divided dry powder containing 2,4-pyrimidinediamine compounds, but the powder can also include a bulking agent, buffer, carrier, excipient, another additive, or the like. Additives can be included in a dry powder formulation of 2,4-pyrimidinediamine compounds, for example, to dilute the powder as required for delivery from the particular powder inhaler, to facilitate processing of the formulation, to provide advantageous powder properties to the formulation, to facilitate dispersion of the powder from the inhalation device, to stabilize to the formulation (e.g., antioxidants or buffers), to provide taste to the formulation, or the like. Typical additives include mono-, di-, and polysaccharides; sugar alcohols and other polyols, such as, for example, lactose, glucose, raffinose, melezitose, lactitol, maltitol, trehalose, sucrose, mannitol, starch, or combinations thereof; surfactants, such as sorbitols, diphosphatidyl choline, or lecithin; and the like.
The present invention also relates to a pharmaceutical composition including 2,4-pyrimidinediamine compounds suitable for administration by inhalation. According to the invention, 2,4-pyrimidinediamine compounds can be used for manufacturing a composition or medicament, including medicaments suitable for administration by inhalation. The invention also relates to methods for manufacturing compositions including 2,4-pyrimidinediamine compounds in a form that is suitable for administration, including administration by inhalation. For example, a dry powder formulation can be manufactured in several ways, using conventional techniques, such as described in any of the publications mentioned above and incorporated expressly herein by reference, and, for example, Baker, et al., U.S. Pat. No. 5,700,904, the entire disclosure of which is incorporated expressly herein by reference. Particles in the size range appropriate for maximal deposition in the lower respiratory tract can be made by micronizing, milling, or the like. And a liquid formulation can be manufactured by dissolving the 2,4-pyrimidinediamine compounds in a suitable solvent, such as water, at an appropriate pH, including buffers or other excipients.
Pharmaceutical compositions comprising the 2,4-pyrimidinediamine compounds described herein (or prodrugs thereof) can be manufactured by means of conventional mixing, dissolving, granulating, dragee-making levigating, emulsifying, encapsulating, entrapping, or lyophilization processes. The compositions can be formulated in conventional manner using one or more physiologically acceptable carriers, diluents, excipients, or auxiliaries which facilitate processing of the active compounds into preparations which can be used pharmaceutically.
For ocular administration, the 2,4-pyrimidinediamine compound(s) or prodrug(s) can be formulated as a solution, emulsion, suspension, etc., suitable for administration to the eye. A variety of vehicles suitable for administering compounds to the eye are known in the art. Specific non-limiting examples are described in U.S. Pat. Nos. 6,261,547; 6,197,934; 6,056,950; 5,800,807; 5,776,445; 5,698,219; 5,521,222; 5,403,841; 5,077,033; 4,882,150; and 4,738,851.
For prolonged delivery, the 2,4-pyrimidinediamine compound(s) or prodrug(s) can be formulated as a depot preparation for administration by implantation or intramuscular injection. The active ingredient can be formulated with suitable polymeric or hydrophobic materials (e.g., as an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble derivatives (e.g., as a sparingly soluble salt). Alternatively, transdermal delivery systems manufactured as an adhesive disc or patch which slowly releases the active compound(s) for percutaneous absorption can be used. To this end, permeation enhancers can be used to facilitate transdermal penetration of the active compound(s). Suitable transdermal patches are described in, for example, U.S. Pat. Nos. 5,407,713.; 5,352,456; 5,332,213; 5,336,168; 5,290,561; 5,254,346; 5,164,189; 5,163,899; 5,088,977; 5,087,240; 5,008,110; and 4,921,475.
Alternatively, other pharmaceutical delivery systems can be employed. Liposomes and emulsions are well-known examples of delivery vehicles that can be used to deliver active compound(s) or prodrug(s). Certain organic solvents such as dimethylsulfoxide (DMSO) may also be employed, although usually at the cost of greater toxicity.
The pharmaceutical compositions may, if desired, be presented in a pack or dispenser device which may contain one or more unit dosage forms containing the active compound(s). The pack may, for example, comprise metal or plastic foil, such as a blister pack. The pack or dispenser device can be accompanied by instructions for administration.
The 2,4-pyrimidinediamine compound(s) or prodrug(s) described herein, or compositions thereof, will generally be used in an amount effective to achieve the intended result, for example, in an amount effective to treat or prevent the particular condition being treated. The compound(s) can be administered therapeutically to achieve therapeutic benefit or prophylactically to achieve prophylactic benefit. By therapeutic benefit is meant eradication or amelioration of the underlying disorder being treated and/or eradication or amelioration of one or more of the symptoms associated with the underlying disorder such that the patient reports an improvement in feeling or condition, notwithstanding that the patient may still be afflicted with the underlying disorder. For example, administration of a compound to a patient suffering from an allergy provides therapeutic benefit not only when the underlying allergic response is eradicated or ameliorated, but also when the patient reports a decrease in the severity or duration of the symptoms associated with the allergy following exposure to the allergen. As another example, therapeutic benefit in the context of asthma includes an improvement in respiration following the onset of an asthmatic attack or a reduction in the frequency or severity of asthmatic episodes. As another specific example, therapeutic benefit in the context of transplantation rejection includes the ability to alleviate an acute rejection episode, such as, for example, HVGR or GVHR, or the ability to prolong the time period between onset of acute rejection episodes and/or onset of chronic rejection. Therapeutic benefit also includes halting or slowing the progression of the disease, regardless of whether improvement is realized.
The amount of compound administered will depend upon a variety of factors, including, for example, the particular condition being treated, the mode of administration, the severity of the condition being treated, the age and weight of the patient, the bioavailability of the particular active compound. Determination of an effective dosage is well within the capabilities of those skilled in the art.
As known by those of skill in the art, the preferred dosage of 2,4-pyrimidinediamine compounds will also depend on the age, weight, general health, and severity of the condition of the individual being treated. Dosage may also need to be tailored to the sex of the individual and/or the lung capacity of the individual, where administered by inhalation. Dosage may also be tailored to individuals suffering from more than one condition or those individuals who have additional conditions which affect lung capacity and the ability to breathe normally, for example, emphysema, bronchitis, pneumonia, and respiratory infections. Dosage, and frequency of administration of the compounds or prodrugs thereof, will also depend on whether the compounds are formulated for treatment of acute episodes of a condition or for the prophylactic treatment of a disorder. For example, acute episodes of allergic conditions, including allergy-related asthma, transplant rejection, etc. A skilled practitioner will be able to determine the optimal dose for a particular individual.
For prophylactic administration, the compound can be administered to a patient at risk of developing one of the previously described conditions. For example, if it is unknown whether a patient is allergic to a particular drug, the compound can be administered prior to administration of the drug to avoid or ameliorate an allergic response to the drug. Alternatively, prophylactic administration can be applied to avoid the onset of symptoms in a patient diagnosed with the underlying disorder. For example, a compound can be administered to an allergy sufferer prior to expected exposure to the allergen. Compounds may also be administered prophylactically to healthy individuals who are repeatedly exposed to agents known to one of the above-described maladies to prevent the onset of the disorder. For example, a compound can be administered to a healthy individual who is repeatedly exposed to an allergen known to induce allergies, such as latex, in an effort to prevent the individual from developing an allergy. Alternatively, a compound can be administered to a patient suffering from asthma prior to partaking in activities which trigger asthma attacks to lessen the severity of, or avoid altogether, an asthmatic episode.
In the context of transplant rejection, the compound can be administered while the patient is not having an acute rejection reaction to avoid the onset of rejection and/or prior to the appearance of clinical indications of chronic rejection. The compound can be administered systemically to the patient as well as administered to the tissue or organ prior to transplanting the tissue or organ in the patient.
The amount of compound administered will depend upon a variety of factors, including, for example, the particular indication being treated, the mode of administration, whether the desired benefit is prophylactic or therapeutic, the severity of the indication being treated and the age and weight of the patient, and the bioavailability of the particular active compound. Determination of an effective dosage is well within the capabilities of those skilled in the art.
Effective dosages can be estimated initially from in vitro assays. For example, an initial dosage for use in animals can be formulated to achieve a circulating blood or serum concentration of active compound that is at or above an IC50 of the particular compound as measured in as in vitro assay. Calculating dosages to achieve such circulating blood or serum concentrations taking into account the bioavailability of the particular compound is well within the capabilities of skilled artisans. For guidance, the reader is referred to Fingl & Woodbury, “General Principles,” In: Goodman and Gilman's The Pharmaceutical Basis of Therapeutics, Chapter 1, pp. 1-46, latest edition, Pergamagon Press, and the references cited therein.
Initial dosages can also be estimated from in vivo data, such as animal models. Animal models useful for testing the efficacy of compounds to treat or prevent the various diseases described above are well-known in the art. Suitable animal models of hypersensitivity or allergic reactions are described in Foster, (1995) Allergy 50(21Suppl):6-9, discussion 34-38 and Tumas et al., (2001), J. Allergy Clin. Immunol 107(6):1025-1033. Suitable animal models of allergic rhinitis are described in Szelenyi et al., (2000), Arzneimittelforschung 50(11):1037-42; Kawaguchi et al., (1994), Clin. Exp. Allergy 24(3):238-244 and Sugimoto et al., (2000), Immunopharmacology 48(1):1-7. Suitable animal models of allergic conjunctivitis are described in Carreras et al., (1993), Br. J. Opthalmol. 77(8):509-514; Saiga et al., (1992), Ophthalmic Res. 24(1):45-50; and Kunert et al., (2001), Invest. Opthalmol. Vis. Sci. 42(11):2483-2489. Suitable animal models of systemic mastocytosis are described in O'Keefe et al., (1987), J. Vet. Intern. Med. 1(2):75-80 and Bean-Knudsen et al., (1989), Vet. Pathol. 26(1):90-92. Suitable animal models of hyper IgE syndrome are described in Claman et al., (1990), Clin. Immunol. Immunopathol. 56(1):46-53. Suitable animal models of B-cell lymphoma are described in Hough et al., (1998), Proc. Natl. Acad. Sci. USA 95:13853-13858 and Hakim et al., (1996), J. Immunol. 157(12):5503-5511. Suitable animal models of atopic disorders such as atopic dermatitis, atopic eczema, and atopic asthma are described in Chan et al., (2001), J. Invest. Dermatol. 117(4):977-983 and Suto et al., (1999), Int. Arch. Allergy Immunol. 120(Suppl 1):70-75. Suitable animal models of transplant rejection, such as models of HVGR, are described in O'Shea et al., (2004), Nature Reviews Drug Discovery 3:555-564; Cetkovic-Curlje & Tibbles, (2004), Current Pharmaceutical Design 10:1767-1784; and Chengelian et al., (2003), Science 302:875-878. Ordinarily skilled artisans can routinely adapt such information to determine dosages suitable for human administration.
Dosage amounts will typically be in the range of from about 0.0001 or 0.001 or 0.01 mg/kg/day to about 100 mg/kg/day, but can be higher or lower, depending upon, among other factors, the activity of the compound, its bioavailability, the mode of administration, and various factors discussed above. Dosage amount and interval can be adjusted individually to provide plasma levels of the compound(s) which are sufficient to maintain therapeutic or prophylactic effect. For example, the compounds can be administered once per week, several times per week (e.g., every other day), once per day, or multiple times per day, depending upon, among other things, the mode of administration, the specific indication being treated, and the judgment of the prescribing physician. In cases of local administration or selective uptake, such as local topical administration, the effective local concentration of active compound(s) may not be related to plasma concentration. Skilled artisans will be able to optimize effective local dosages without undue experimentation.
Preferably, the compound(s) will provide therapeutic or prophylactic benefit without causing substantial toxicity. Toxicity of the compound(s) can be determined using standard pharmaceutical procedures. The dose ratio between toxic and therapeutic (or prophylactic) effect is the therapeutic index. Compounds(s) that exhibit high therapeutic indices are preferred.
The foregoing disclosure pertaining to the dosage requirements for the 2,4-substituted pyrimidinediamine compounds is pertinent to dosages required for prodrugs, with the realization, apparent to the skilled artisan, that the amount of prodrug(s) administered will also depend upon a variety of factors, including, for example, the bioavailability of the particular prodrug(s) and the conversation rate and efficiency into active drug compound under the selected route of administration. Determination of an effective dosage of prodrug(s) for a particular use and mode of administration is well within the capabilities of those skilled in the art.
Effective dosages can be estimated initially from in vitro activity and metabolism assays. For example, an initial dosage of prodrug for use in animals can be formulated to achieve a circulating blood or serum concentration of the metabolite active compound that is at or above an IC50 of the particular compound as measured in as in vitro assay, such as the in vitro CHMC or BMMC and other in vitro assays described in U.S. application Ser.

F. General Synthesis of the Compounds of the Invention
The 2,4-pyrimidinediamine compounds and prodrugs of the invention may be synthesized via a variety of different synthetic routes using commercially available starting materials and/or starting materials prepared by conventional synthetic methods. Suitable exemplary methods that may be routinely adapted to synthesize the 2,4-pyrimidinediamine compounds and prodrugs of the invention are found in U.S. Pat. No. 5,958,935, the disclosure of which is incorporated herein by reference. Specific examples describing the synthesis of numerous 2,4-pyrimidinediamine compounds and prodrugs, as well as intermediates therefore, are described in copending U.S. application Ser. No. 10/355,543, filed Jan. 31, 2003 (US2004/0029902A1), the contents of which are incorporated herein by reference. Suitable exemplary methods that may be routinely used and/or adapted to synthesize active 2,4-substituted pyrimidinediamine compounds can also be found in international application Serial No. PCT/US03/03022 filed Jan. 31, 2003 (WO 03/063794), U.S. application Ser. No. 10/631,029 filed Jul. 29, 2003, international application Serial No. PCT/US03/24087 (WO2004/014382), U.S. application Ser. No. 10/903,263 filed Jul. 30, 2004, and international application Serial No. PCT/US2004/24716 (WO005/016893), the disclosures of which are incorporated herein by reference. All of the compounds described herein (including prodrugs) may be prepared by routine adaptation of these methods.
Specific exemplary synthetic methods for the 2,4-substituted pyrimidinediamines described herein are also described in Example 1, below. Those of skill in the art will also be able to readily adapt these examples for the synthesis of additional 2,4-substituted pyrimidinediamines as described herein.
A variety of exemplary synthetic routes that can be used to synthesize the 2,4-pyrimidinediamine compounds of the invention are described in Schemes (I)-(VII), below. These methods may be routinely adapted to synthesize the 2,4-substituted pyrimidinediamine compounds and prodrugs described herein.
In one exemplary embodiment, the compounds can be synthesized from substituted or unsubstituted uracils as illustrated in Scheme (I), below:
Figure US08299087-20121030-C00018
In Scheme (I), ring A, ring B, R1, (R2)q, (R3)p, X, Y and alk are as defined herein. According to Scheme (I), uracil A-1 is dihalogenated at the 2- and 4-positions using a standard halogenating agent such as POCl3 (or other standard halogenating agent) under standard conditions to yield 2,4-dichloropyrimidine A-2. Depending upon the X substituent, in pyrimidinediamine A-2, the chloride at the C4 position is more reactive towards nucleophiles than the chloride at the C2 position. This differential reactivity can be exploited to synthesize 2,4-pyrimidinediamines A-7 by first reacting 2,4-dichloropyrimidine A-2 with one equivalent of amine A-3, yielding 4N-substituted-2-chloro-4-pyrimidineamine A-4, followed by amine A-5 to yield a 2,4-pyrimidinediamine derivative A-6, where N4 nitrogen can be selectively alkylated to give compounds of formula I.
Typically, the C4 halide is more reactive towards nucleophiles, as illustrated in the Scheme. However, as will be recognized by skilled artisans, the identity of the X substituent may alter this reactivity. For example, when X is trifluoromethyl, a 50:50 mixture of 4N-substituted-4-pyrimidineamine A-4 and the corresponding 2N-substituted-2-pyrimidineamine is obtained. The regioselectivity of the reaction can also be controlled by adjusting the solvent and other synthetic conditions (such as temperature), as is well-known in the art.
The reactions depicted in Scheme (I) may proceed more quickly when the reaction mixtures are heated via microwave. When heating in this fashion, the following conditions can be used: heat to 175° C. in ethanol for 5-20 min. in a Smith Reactor (Personal Chemistry, Uppsala, Sweden) in a sealed tube (at 20 bar pressure).
The uracil A-1 starting materials can be purchased from commercial sources or prepared using standard techniques of organic chemistry. Commercially available uracils that can be used as starting materials in Scheme (I) include, by way of example and not limitation, uracil (Aldrich #13,078-8; CAS Registry 66-22-8); 5-bromouracil (Aldrich #85, 247-3; CAS Registry 51-20-7; 5-fluorouracil (Aldrich #85, 847-1; CAS Registry 51-21-8); 5-iodouracil (Aldrich #85, 785-8; CAS Registry 696-07-1); 5-nitrouracil (Aldrich #85, 276-7; CAS Registry 611-08-5); 5-(trifluoromethyl)-uracil (Aldrich #22, 327-1; CAS Registry 54-20-6). Additional 5-substituted uracils are available from General Intermediates of Canada, Inc., Edmonton, Calif. and/or Interchim, Cedex, France, or can be prepared using standard techniques. Myriad textbook references teaching suitable synthetic methods are provided infra.
Amines A-3 and A-5 can be purchased from commercial sources or, alternatively, can be synthesized utilizing standard techniques. For example, suitable amines can be synthesized from nitro precursors using standard chemistry. Specific exemplary reactions are provided in the Examples section. See also Vogel, 1989, Practical Organic Chemistry, Addison Wesley Longman, Ltd. and John Wiley & Sons, Inc.
Skilled artisans will recognize that in some instances, amines A-3 and A-5 and/or substituent X on uracil A-1 may include functional groups that require protection during synthesis. The exact identity of any protecting group(s) used will depend upon the identity of the functional group being protected, and will be apparent to those of skill in the art. Guidance for selecting appropriate protecting groups, as well as synthetic strategies for their attachment and removal, can be found, for example, in Greene & Wuts, Protective Groups in Organic Synthesis, 3d Edition, John Wiley & Sons, Inc., New York (1999) and the references cited therein (hereinafter “Greene & Wuts”).
Thus, protecting group refers to a group of atoms that, when attached to a reactive functional group in a molecule, mask, reduce or prevent the reactivity of the functional group. Typically, a protecting group can be selectively removed as desired during the course of a synthesis. Examples of protecting groups can be found in Greene and Wuts, as mentioned above, and additionally, in Harrison et al., Compendium of Synthetic Organic Methods, Vols. 1-8, 1971-1996, John Wiley & Sons, NY. Representative amino protecting groups include, but are not limited to, formyl, acetyl, trifluoroacetyl, benzyl, benzyloxycarbonyl (“CBZ”), tert-butoxycarbonyl (“Boc”), trimethylsilyl (“TMS”), 2-trimethylsilyl-ethanesulfonyl (“TES”), trityl and substituted trityl groups, allyloxycarbonyl, 9-fluorenylmethyloxycarbonyl (“FMOC”), nitro-veratryloxycarbonyl (“NVOC”) and the like. Representative hydroxyl protecting groups include, but are not limited to, those where the hydroxyl group is either acylated to form acetate and benzoate esters or alkylated to form benzyl and trityl ethers, as well as alkyl ethers, tetrahydropyranyl ethers, trialkylsilyl ethers (e.g., TMS or TIPPS groups) and allyl ethers.
A specific embodiment of Scheme (I) utilizing 5-fluorouracil (Aldrich #32, 937-1) as a starting material is illustrated in Scheme (Ia), below:
Figure US08299087-20121030-C00019
In Scheme (Ia), ring A, ring B, R1, (R2)q, (R3)p, Y, and alk are as previously defined for Scheme (I). Asymmetric 2N,4N-disubstituted-5-fluoro-2,4-pyrimidinediamine A-11 can be obtained by reacting 2,4-dichloro-5-fluoropyrimidine A-9 with one equivalent of amine A-3 (to yield 2-chloro-N4-substituted-5-fluoro-4-pyrimidineamine A-10) followed by one or more equivalents of amine A-5.
In another exemplary embodiment, the 2,4-pyrimidinediamine compounds of the invention can be synthesized from substituted or unsubstituted cytosines as illustrated in Schemes (IIa) and (IIb), below:
Figure US08299087-20121030-C00020
Figure US08299087-20121030-C00021
In Schemes (IIa) and (IIb), ring A, ring B, R1, (R2)q, (R3)p, X, Y, and alk are as previously defined for Scheme (I) and PG represents a protecting group. Referring to Scheme (IIa), the C4 exocyclic amine of cytosine A-12 is first protected with a suitable protecting group PG to yield N4-protected cytosine A-13. For specific guidance regarding protecting groups useful in this context, see Vorbrüggen and Ruh-Pohlenz, 2001, Handbook of Nucleoside Synthesis, John Wiley & Sons, NY, pp. 1-631 (“Vorbrüggen”). Protected cytosine A-13 is halogenated at the C2 position using a standard halogenation reagent under standard conditions to yield 2-chloro-4N-protected-4-pyrimidineamine A-14. Reaction with amine A-5 gives A-15, which on deprotection of the C4 exocyclic amine, gives A-16. Reaction of A-16 with amine A-3 yields 2,4-pyrimidinediamine derivative A-6.
Alternatively, referring to Scheme (IIb), cytosine A-12 can be reacted with amine A-3 or protected amine A-1 g to yield N4-substituted cytosine A-17 or A-20, respectively. These substituted cytosines may then be halogenated as previously described, deprotected (in the case of N4-substituted cytosine A-20) and reacted with amine A-5 to yield a 2,4-pyrimidinediamine A-6.
Commercially-available cytosines that can be used as starting materials in Schemes (IIa) and (IIb) include, but are not limited to, cytosine (Aldrich #14, 201-8; CAS Registry 71-30-7); N4-acetylcytosine (Aldrich #37, 791-0; CAS Registry 14631-20-0); 5-fluorocytosine (Aldrich #27, 159-4; CAS Registry 2022-85-7); and 5-(trifluoromethyl)-cytosine. Other suitable cytosines useful as starting materials in Schemes (IIa) are available from General Intermediates of Canada, Inc., Edmonton, Calif. and/or Interchim, Cedex, France, or can be prepared using standard techniques. Myriad textbook references teaching suitable synthetic methods are provided infra.
In still another exemplary embodiment, the 2,4-pyrimidinediamine compounds of the invention can be synthesized from substituted or unsubstituted 2-amino-4-pyrimidinols as illustrated in Scheme (III), below:
Figure US08299087-20121030-C00022
In Scheme (III), ring A, ring B, R1, (R2)q, (R3)p, X, Y, and alk are as previously defined for Scheme (I) and LG is a leaving group as discussed in more detail in connection with Scheme IV, infra. Referring to Scheme (III), 2-amino-4-pyrimidinol A-22 is reacted with arylating agent A-23 to yield N2-substituted-4-pyrimidinol A-24, which is then halogenated as previously described to yield N2-substituted-4-halo-2-pyrimidineamine A-25. Further reaction with amine A-3 affords a 2,4-pyrimidinediamine derivative A-6.
Suitable commercially-available 2-amino-4-pyrimidinols A-22 that can be used as starting materials in Scheme (III) are available from General Intermediates of Canada, Inc., Edmonton, Calif. and/or Interchim, Cedex, France, or can be prepared using standard techniques. Myriad textbook references teaching suitable synthetic methods are provided infra.
Alternatively, the 2,4-pyrimidinediamine compounds of the invention can be prepared from substituted or unsubstituted 4-amino-2-pyrimidinols as illustrated in Scheme (IV), below:
Figure US08299087-20121030-C00023
In Scheme (IV), ring A, ring B, R1, (R2)q, (R3)p, X, Y, and alk are as previously defined for Scheme (I). Referring to Scheme (IV), the C2-hydroxyl of 4-amino-2-pyrimidinol A-26 is more reactive towards nucleophiles than the C4-amino such that reaction with amine A-5 yields N2-substituted-2,4-pyrimidinediamine A-27. Subsequent reaction with compound A-28, which includes a suitable leaving group, or amine A-3 yields a 2,4-pyrimidinediamine derivative A-6. Compound A-28 may include virtually any leaving group that can be displaced by the C4-amino of N2-substituted-2,4-pyrimidinediamine A-27. Suitable leaving groups include, but are not limited to, halogens, methanesulfonyloxy (mesyloxy; “OMs”), trifluoromethanesulfonyloxy (“OTf”) and p-toluenesulfonyloxy (tosyloxy; “OTs”), benzene sulfonyloxy (“besylate”) and m-nitro benzene sulfonyloxy (“nosylate”). Other suitable leaving groups will be apparent to those of skill in the art.
Substituted 4-amino-2-pyrimidinol starting materials can be obtained commercially or synthesized using standard techniques. Myriad textbook references teaching suitable synthetic methods are provided infra.
In still another exemplary embodiment, the 2,4-pyrimidinediamine compounds of the invention can be prepared from 2-chloro-4-aminopyrimidines or 2-amino-4-chloropyrimidines as illustrated in Scheme (V), below:
Figure US08299087-20121030-C00024
In Scheme (V), ring A, ring B, R1, (R2)q, (R3)p, X, Y, and alk are as defined for Scheme (I) and leaving group is as defined for Scheme (IV). Referring to Scheme (V), 2-amino-4-chloropyrimidine A-29 is reacted with amine A-3 to yield 4N-substituted-2,4-pyrimidinediamine A-30 which, following reaction with compound A-23 or amine A-5, yields a N2,N4-2,4-pyrimidinediamine derivative A-6. Alternatively, 2-chloro-4-amino-pyrimidine A-31 can be reacted with compound A-28 to give compound A-32 which on reaction with amine A-5 yields A-6.
A variety of pyrimidines A-29 and A-31 suitable for use as starting materials in Scheme (V) are commercially available from General Intermediates of Canada, Inc., Edmonton, Calif. and/or Interchim, Cedex, France, or can be prepared using standard techniques. Myriad textbook references teaching suitable synthetic methods are provided infra.
Alternatively, 4-chloro-2-pyrimidineamines A-29 can be prepared as illustrated in Scheme (Va):
Figure US08299087-20121030-C00025
In Scheme (Va), X is as previously defined for Scheme I. In Scheme (Va), dialdehyde A-33 is reacted with guanidine to yield 2-pyrimidineamine A-34. Reaction with a peracid such as m-chloroperbenzoic acid, trifluoroperacetic acid or urea hydrogen peroxide complex yields N-oxide A-35, which is then halogenated to give 4-chloro-2-pyrimidineamine A-29. The corresponding 4-halo-2-pyrimidineamines can be obtained by using suitable halogenation reagents.
In yet another exemplary embodiment, the 2,4-pyrimidinediamine compounds of the invention can be prepared from substituted or unsubstituted uridines as illustrated in Scheme (VI), below:
Figure US08299087-20121030-C00026
In Scheme (VI), ring A, ring B, R1, (R2)q, (R3)p, X, Y, and alk are as previously defined for Scheme (I) and PG represents a protecting group, as discussed in connection with Scheme (IIb). According to Scheme (VI), uridine A-36 has a C4 reactive center such that reaction with amine A-3 or protected amine A-19 yields N4-substituted cytidine A-37 or A-38, respectively. Acid-catalyzed deprotection of N4-substituted A-37 or A-38 (when “PG” represents an acid-labile protecting group) yields N4-substituted cytosine A-39, which can be subsequently halogenated at the C2-position and reacted with amine A-5 to yield a 2,4-pyrimidinediamine derivative A-6.
Cytidines may also be used as starting materials in an analogous manner, as illustrated in Scheme (VII), below:
Figure US08299087-20121030-C00027
In Scheme (VII), ring A, ring B, R1, (R2)q, (R3)p, X, Y, and alk are as previously defined in Scheme (I) and PG represents a protecting group as discussed above. Referring to Scheme (VII), like uridine A-36, cytidine A-40 has a C4 reactive center such that reaction with amine A-3 or protected amine A-19 yields N4-substituted cytidine A-37 or A-38, respectively. These cytidines A-37 and A-38 are then treated as previously described for Scheme (VI) to yield a 2,4-pyrimidinediamine derivative A-6.
Although Schemes (VI) and (VII) are exemplified with ribosylnucleosides, skilled artisans will appreciate that the corresponding 2′-deoxyribo and 2′,3′-dideoxyribo nucleosides, as well as nucleosides including sugars or sugar analogs other than ribose, would also work.
Numerous uridines and cytidines useful as starting materials in Schemes (VI) and (VII) are known in the art, and include, by way of example and not limitation, 5-trifluoromethyl-2′-deoxycytidine (Chem. Sources #ABCR F07669; CAS Registry 66, 384-66-5); 5-bromouridine (Chem. Sources Int'l 2000; CAS Registry 957-75-5); 5-iodo-2′-deoxyuridine (Aldrich #1-775-6; CAS Registry 54-42-2); 5-fluorouridine (Aldrich #32, 937-1; CAS Registry 316-46-1); 5-iodouridine (Aldrich #85, 259-7; CAS Registry 1024-99-3); 5-(trifluoromethyl)uridine (Chem.

Additional uridines and cytidines that can be used as starting materials in Schemes (VI) and (VII) are available from General Intermediates of Canada, Inc., Edmonton, Calif. and/or Interchim, Cedex, France, or can be prepared using standard techniques. Myriad textbook references teaching suitable synthetic methods are provided infra.
Although many of the synthetic schemes discussed above do not illustrate the use of protecting groups, skilled artisans will recognize that in some instances certain substituents, such as, for example, R2 and/or R4, may include functional groups requiring protection. The exact identity of the protecting group used will depend upon, among other things, the identity of the functional group being protected and the reaction conditions used in the particular synthetic scheme, and will be apparent to those of skill in the art. Guidance for selecting protecting groups, their attachment and removal suitable for a particular application can be found, for example, in Greene & Wuts, supra.
Prodrugs as described herein can be prepared by routine modification of the above-described methods. Alternatively, such prodrugs can be prepared by reacting a suitably protected 2,4-pyrimidinediamine 6 with a suitable progroup. Conditions for carrying out such reactions and for deprotecting the product to yield a prodrug as described herein are well-known.

Those of skill in the art will appreciate that the 2,4-pyrimidinediamine compounds described herein may include functional groups that can be masked with progroups to create prodrugs. Such prodrugs are usually, but need not be, pharmacologically inactive until converted into their active drug form. Indeed, many of the 2,4-pyrimidinediamine compounds described in this invention include promoieties that are hydrolyzable or otherwise cleavable under conditions of use. For example, ester groups commonly undergo acid-catalyzed hydrolysis to yield the parent carboxylic acid when exposed to the acidic conditions of the stomach, or base-catalyzed hydrolysis when exposed to the basic conditions of the intestine or blood. Thus, when administered to a subject orally, 2,4-pyrimidinediamine compounds that include ester moieties can be considered prodrugs of their corresponding carboxylic acid, regardless of whether the ester form is pharmacologically active.
The mechanism by which the progroup(s) metabolizes is not critical, and can be caused by, for example, hydrolysis under the acidic conditions of the stomach, as described above, and/or by enzymes present in the digestive tract and/or tissues or organs of the body. Indeed, the progroup(s) can be selected to metabolize at a particular site within the body. For example, many esters are cleaved under the acidic conditions found in the stomach. Prodrugs designed to cleave chemically in the stomach to the active 2,4-pyrimidinediamine can employ progroups including such esters. Alternatively, the progroups can be designed to metabolize in the presence of enzymes such as esterases, amidases, lipases, phosphatases including ATPases and kinase etc. Progroups including linkages capable of metabolizing in vivo are well-known, and include, by way of example and not limitation, ethers, thioethers, silylethers, silylthioethers, esters, thioesters, carbonates, thiocarbonates, carbamates, thiocarbamates, ureas, thioureas, carboxamides, etc. In some instances, a “precursor” group that is oxidized by oxidative enzymes such as, for example, cytochrome P450 of the liver, to a metabolizable group, can be selected.
In the prodrugs, any available functional moiety can be masked with a progroup to yield a prodrug. Functional groups within the 2,4-pyrimidinediamine compounds that can be masked with progroups for inclusion in a promoiety include, but are not limited to, amines (primary and secondary), hydroxyls, sulfanyls (thiols), carboxyls, etc. Myriad progroups suitable for masking such functional groups to yield promoieties that are cleavable under the desired conditions of use are known in the art. All of these progroups, alone or in combinations, can be included in the prodrugs.
In some embodiments of the 2,4-pyrimidinediamine compounds and methods of using the compounds, the progroup(s) can be attached to any available primary or secondary amine, including, for example, the N2 nitrogen atom of the 2,4-pyrimidinediamine moiety, the N4 nitrogen atom of the 2,4-pyrimidinediamine moiety, and/or a primary or secondary nitrogen atom included in a substituent on the 2,4-pyrimidinediamine compound.
In particular embodiments of the 2,4-pyrimidinediamine compounds and methods of using the compounds, the prodrugs described herein are 2,4-pyrimidinediamine compounds that are substituted at the N4 nitrogen of the 2,4-pyrimidinediamine moiety with a substituted or unsubstituted nitrogen-containing bicyclic ring that includes at least one progroup at one or more of: the nitrogen atom(s) of the bicyclic ring, the N2 nitrogen of the 2,4-pyrimidinediamine moiety and/or the N4 nitrogen of the 2,4-pyrimidinediamine moiety.
As noted above, the identity of the progroup is not critical, provided that it can be metabolized under the desired conditions of use, for example under the acidic conditions found in the stomach and/or by enzymes found in vivo, to yield a the biologically active group, e.g., the 2,4-substituted pyrimidinediamines as described herein. Thus, skilled artisans will appreciate that the progroup can comprise virtually any known or later-discovered hydroxyl, amine or thiol protecting group. Non-limiting examples of suitable protecting groups can be found, for example, in Protective Groups in Organic Synthesis, Greene & Wuts, 2nd Ed., John Wiley & Sons, New York, 1991 (especially pages 10-142 (alcohols, 277-308 (thiols) and 309-405 (amines) the disclosure of which is incorporated herein by reference).
Additionally, the identity of the progroup(s) can also be selected so as to impart the prodrug with desirable characteristics. For example, lipophilic groups can be used to decrease water solubility and hydrophilic groups can be used to increase water solubility. In this way, prodrugs specifically tailored for selected modes of administration can be obtained. The progroup can also be designed to impart the prodrug with other properties, such as, for example, improved passive intestinal absorption, improved transport-mediated intestinal absorption, protection against fast metabolism (slow-release prodrugs), tissue-selective delivery, passive enrichment in target tissues, targeting-specific transporters, etc. Groups capable of imparting prodrugs with these characteristics are well-known, and are described, for example, in Ettmayer et al., 2004, J. Med. Chem. 47(10):2393-2404, the disclosure of which is incorporated by reference. All of the various groups described in these references can be utilized in the prodrugs described herein.

Example 2 Assay for Ramos B-Cell Line Stimulated with IL-4
B-cells stimulated with cytokine Interleukin-4 (IL-4) activate the JAK/Stat pathway through phosphorylation of the JAK family kinases, JAK-1 and JAK-3, which in turn phosphorylate and activate the transcription factor Stat-6. One of the genes upregulated by activated Stat-6 is the low affinity IgE receptor, CD23. To study the effect of inhibitors on the JAK family kinases, human Ramos B cells were stimulated with human IL-4.
The Ramos B-cell line was acquired from ATCC (ATCC Catalog No. CRL-1596). The cells were cultured in RPMI 1640 (Cellgro, MediaTech, Inc., Herndon, Va., Cat No. 10-040-CM) with 10% fetal bovine serum (FBS), heat inactivated (JRH Biosciences, Inc, Lenexa, Kans., Cat No. 12106-500M) according to ATCC propagation protocol. Cells were maintained at a density of 3.5×105. The day before the experiment, Ramos B-cells were diluted to 3.5×105 cells/mL to ensure that they were in a logarithmic growth phase.
Cells were spun down and suspended in RPMI with 5% serum. 5×104 cells were used per point in a 96-well tissue culture plate. Cells were pre-incubated with compound or DMSO (Sigma-Aldrich, St. Louis, Mo., Cat No. D2650) vehicle control for 1 hour in a 37° C. incubator. Cells were then stimulated with IL-4 (Peprotech Inc., Rocky Hill, N.J., Cat No. 200-04) for a final concentration of 50 units/mL for 20-24 hours. Cells were then spun down and stained with anti-CD23-PE(BD Pharmingen, San Diego, Calif., Cat No. 555711) and analyzed by FACS. Detection was performed using a BD LSR I System Flow Cytometer, purchased from Becton Dickinson Biosciences of San Jose, Calif. The IC50 calculated based on the results of this assay are provided in Table IX.
Example 3 Assay for Ramos B-Cell Line Stimulated with IL-2
Primary human T-cells derived from peripheral blood and pre-activated through stimulation of the T-cell receptor and CD28, proliferate in vitro in response to the cytokine Interleukin-2 (IL-2). This proliferative response is dependent on the activation of JAK-1 and JAK-3 tyrosine kinases, which phosphorylate and activate the transcription factor Stat-5.
Human primary T cells were prepared as follows. Whole blood was obtained from a healthy volunteer, mixed 1:1 with PBS, layered on to Ficoll Hypaque (Amersham Pharmacia Biotech, Piscataway, N.J., Catalog #17-1440-03) in 2:1 blood/PBS:ficoll ratio and centrifuged for 30 min at 4° C. at 1750 rpm. The lymphocytes at the serum: ficoll interface were recovered and washed twice with 5 volumes of PBS. The cells were resuspended in Yssel's medium (Gemini Bio-products, Woodland, Calif., Catalog #400-103) containing 40 U/mL recombinant IL2 (R and D Systems, Minneapolis, Minn., Catalog #202-IL (20 μg)) and seeded into a flask pre-coated with 1 μg/mL anti-CD3 (BD Pharmingen, San Diego, Calif., Catalog #555336) and 5 μg/mL anti-CD28 (Immunotech, Beckman Coulter of Brea Calif., Catalog #1M1376). The primary T-cells were stimulated for 3-4 days, then transferred to a fresh flask and maintained in RPMI with 10% FBS and 40 U/mL IL-2.
Primary T-cells were washed twice with PBS to remove the IL-2 and resuspended in Yssel's medium at 2×106 cells/mL. 50 μL of cell suspension containing 80 U/mL IL-2 was added to each well of a flat bottom 96 well black plate. For the unstimulated control, IL-2 was omitted from the last column on the plate. Compounds were serially diluted in dimethyl sulfoxide (DMSO, 99.7% pure, cell culture tested, Sigma-Aldrich, St. Louis, Mo., Catalog No. D2650) from 5 mM in 3-fold dilutions, and then diluted 1:250 in Yssel's medium. 50 μL of 2×compound was added per well in duplicate and the cells were allowed to proliferate for 72 hours at 37° C.
Proliferation was measured using CellTiter-Glo® Luminescent Cell Viability Assay (Promega), which determines the number of viable cells in culture based on quantitation of the ATP present, as an indicator of metabolically active cells. The substrate was thawed and allowed to come to ambient temperature. After mixing the Cell Titer-Glo reagent and diluent together, 100 μL was added to each well. The plates were mixed on an orbital shaker for two minutes to induce lysis and incubated at ambient temperature for an additional ten minutes to allow the signal to equilibrate. Detection was performed using a Wallac Victor2 1420 multilabel counter purchased from Perkin Elmer, Shelton, Conn.
Example 4 A549 Epithelial Line Stimulated with IFNγ
A549 lung epithelial cells up-regulate ICAM-1 (CD54) surface expression in response to a variety of different stimuli. Therefore, using ICAM-1 expression as readout, compound effects on different signaling pathways can be assessed in the same cell type. IFNγ up-regulates ICAM-1 through activation of the JAK/Stat pathway. In this example, the up-regulation of ICAM-1 by IFNγ was assessed.
The A549 lung epithelial carcinoma cell line originated from the American Type Culture Collection. Routine culturing was with F12K media (Mediatech Inc., Lenexa, Kans., Cat. No. 10-025—CV) with 10% fetal bovine serum, 100 I.U. penicillin and 100 ng/mL streptomycin (complete F12k media). Cells were incubated in a humidified atmosphere of 5% CO2 at 37° C. Prior to use in the assay, A549 cells were washed with PBS and trypsinized (Mediatech Inc., Cat. No. 25-052-Cl) to lift the cells. The trypsin cell suspension was neutralized with complete F12K media and centrifuged to pellet the cells. The cell pellet was resuspended in complete F12K media at a concentration of 2.0×105/mL. Cells were seeded at 20,000 per well, 100 μL total volume, in a flat bottom tissue culture plate and allowed to adhere overnight.
On day two, A549 cells were pre-incubated with test compound or DMSO (control) (Sigma-Aldrich, St. Louis, Mo., Catalog No. D2650) for 1 hour. The cells were then stimulated with IFNγ (75 ng/mL) (Peprotech Inc., Rocky Hill, N.J., Cat. No. 300-02) and allowed to incubate for 24 hours. The final test compound dose range was 30 μM to 14 nM in 200 μL F12K media containing 5% FBS, 0.3% DMSO.
On day three, the cell media was removed and the cells were washed with 200 μL PBS (phosphate buffered saline). Each well was trypsinized to dissociate the cells, then neutralized by addition of 200 μL complete F12K media. Cells were pelleted and stained with an APC conjugated mouse anti-human ICAM-1 (CD54)(BD Pharmingen, San Diego, Calif., Catalog #559771) antibody for 20 minutes at 4° C. Cells were washed with ice cold FACS buffer (PBS+2% FBS) and surface ICAM-1 expression was analyzed by flow cytometry. Detection was performed using a BD LSR I System Flow Cytometer, purchased from BD Biosciences of San Jose, Calif. Events were gated for live scatter and the geometric mean was calculated (Becton-Dickinson CellQuest software version 3.3, Franklin Lakes, N.J.). Geometric means were plotted against the compound concentration to generate a dose response curve.
Example 5 U937 IFNγ ICAM1 FACS Assay
Human U937 monocytic cells up-regulate ICAM-1 (CD54) surface expression in response to a variety of different stimuli. Therefore, using ICAM-1 expression as readout, compound effects on different signaling pathways can be assessed in the same cell type. IFNγ up-regulates ICAM-1 through activation of the JAK/Stat pathway. In this example, the up-regulation of ICAM-1 by IFNγ was assessed.
The U937 human monocytic cell line was obtained from ATCC of Rockville Md., catalog number CRL-1593.2, and cultured in RPM1-1640 medium containing 10% (v/v) FCS. U937 cells were grown in 10% RPMI. The cells were then plated at a concentration of 100,000 cells per 160 μL in 96 well flat bottom plates. The test compounds were then diluted as follows: 10 mM test compound was diluted 1:5 in DMSO (3 μL 10 mM test compound in 12 μL DMSO), followed by a 1:3 serial dilution of test compound in DMSO (6 μL test compound serially diluted into 12 μL DMSO to give 3-fold dilutions). Then 4 μL of test compound was transferred to 76 μL of 10% RPMI resulting in a 10× solution (100 μM test compound, 5% DMSO). For control wells, 4 μL of DMSO was diluted into 76 μL 10% RPMI.
The assay was performed in duplicate with 8 points (8 3-fold dilution concentrations from 10 μL) and with 4 wells of DMSO only (control wells) under stimulated conditions and 4 wells of DMSO only under unstimulated conditions.
The diluted compound plate was mixed 2× using a multimek (Beckman Coulter of Brea, Calif.) and then 20 μL of the diluted compounds was transferred to the 96 well plate containing 160 μL of cells, which were then mixed again twice at low speeds. The cells and compounds were then pre-incubated for 30 minutes at 37° C. with 5% CO2.
The 10× stimulation mix was made by preparing a 100 ng/mL solution of human IFNγ in 10% RPMI. The cells and compound were then stimulated with 20 μL of IFNγ stimulation mix to give a final concentration of 10 ng/mL IFNγ, 10 μM test compound, and 0.5% DMSO. The cells were kept under conditions for stimulation for 18-24 hours at 37° C. with 5% CO2.
The cells were transferred to a 96 well round bottom plate for staining and then kept on ice for the duration of the staining procedure. Cells were spun down at 1000 rpm for 5 minutes at 4° C., following which the supernatant was removed. Following removal of the supernatant, 1 μL APC conjugated mouse anti-human ICAM-1 antibody was added per 100 μL FACS buffer. The cells were then incubated on ice in the dark for 30 minutes. Following incubation, 150 μL of FACS buffer was added and the cells were centrifuged at 1000 rpm for 5 minutes at 4° C., following which the supernatant was removed. After removal of the supernatant, 200 μL of FACS buffer was added and the cells were resuspended. After suspension, the cells were centrifuged at 1000 rpm for 5 min at 4° C. Supernatant was then removed prior to resuspension of the cells in 150 μL FACS buffer.
Detection was performed using a BD LSR I System Flow Cytometer, purchased from BD Biosciences of San Jose, Calif. The live cells were gated for live scatter and the geometric mean of ICAM-APC was measured (Becton-Dickinson CellQuest software version 3.3, Franklin Lakes, N.J.). Both % live cells and ICAM-1 expression was analyzed. The assays for the test compounds were carried out in parallel with a control compound of known activity. The EC50 for the control compound is typically 40-100 nM.
